FAQs

How do you find square footage with multiple sides? ›

The formula for calculating the square feet of a polygon is:Area = (number of sides × length of one side × apothem) / 2In this formula, the number of sides refers to the number of straight edges of your shape and the length refers to the length of each of those sides.

How to calculate area of land with 4 unequal sides? ›

Calculating area of land with 4 unequal sides would require you to first, sketch out the land using the dimensions provided. Then make an appropriate diagonal. Next, determine the areas of the two triangles that the diagonal creates. The size of the land is calculated by adding the areas of the two triangles.

How do you calculate square footage with different lengths? ›

To calculate feet squared (or sq. ft. for short), determine the length and width of the area you are working with, measured in feet. Multiply the length by the width and you'll have the square feet.

How do you find the square footage of an irregular shape? ›

Calculate the square footage of an oddly-shaped room

The easiest way to calculate the square footage of an odd-shaped room is to divide it into even shapes, like squares or rectangles. You should then measure each of these shapes and multiply their lengths by their widths.

How do you calculate square footage with 3 sides? ›

Since we know that all three sides are 6 feet long, we can use Heron's formula to work out its area in square feet.
  1. Calculate the perimeter: p = 3 × (6 ft) = 18 ft.
  2. Divide the perimeter in half to get the semiperimeter: s = ½p = 9 ft.
  3. Use Heron's formula: A = √[ s(s−a)(s−b)(s−c) ] A = √[ 9 × (9 − 6)³ ] A = √[ 9 × (3)³ ]

How do you find the area of a shape with multiple sides? ›

Steps to find the area of an irregular shape
  1. Find all the unknown sides.
  2. Divide the irregular shape into squares and rectangles.
  3. Find the area of each individual squares and rectangles.
  4. Add all the individual areas to find the total area of the irregular shape. Total area = sum of all individual areas.

How to calculate sq ft with 4 different sides? ›

First draw a sketch of the land based on the given dimensions. Then draw a suitable diagonal. Now calculate the area of the two triangles formed by the diagonal. Add the area of the two triangles to get the area of the land.

What is the formula for the area of 4 sides? ›

It is rectangle is a four-sided quadrilateral with opposite side as equal. Its area formula is expressed as product of its length and breadth, i.e., A = length × breadth square units.

What is the formula for calculating square footage? ›

The next step in how to calculate square footage is to plug your measurements into the square footage formula: L x W = A (in square feet). How to find square feet: multiply the length measurement in feet by the width measurement (in feet).

How do you find square footage with length and width? ›

Measure the length and width, in feet, of each room. Then, multiply the length by the width to calculate that room's square footage. For example: If a bedroom is 12 feet by 20 feet, it is 240 square feet (12 x 20 = 240). For each room, write the total square footage in the corresponding space on your sketch.

What are the ways of measuring area with irregular shape? ›

Explanation: To find the Area of Irregular shapes, first, we need to divide the Irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth. Then, find the Area of these individual shapes. Add them to get an Area of Irregular shapes.

How to find area and perimeter of irregular shapes? ›

The sum of the areas of each smaller figure is the area of the irregular figure. To find the perimeter of the figure above, use the Pythagorean theorem and circumference formula to find the missing lengths: To find the area of the same figure, divide the figure into one triangle, two rectangles, and one semi-circle.

How do you calculate square feet of all sides are different? ›

1 square meter = 10.764 square feet So, total area of land = 41.52 X 10.764 = 446.921 square feet. You just have to multiply the area by 10.764 to get the value in square feet. This makes you sure about how to calculate irregular land areas.

How to calculate a 5 sided area? ›

Area of Pentagon Formula if only Side is Known
  1. A=14√5(5+2√5)s2.
  2. Area of Pentagon = 14√5(5+2√5)s2.
  3. Area of Pentagon = 14√5(5+2√5)s2.
