Calculate the area of rectangles using the formula area A = length L x width W
Home / 5th grade / Algebra / Formulae: area / Area of rectangles
To calculate the area of a rectangle, you will need to know the lengths of its longer and shorter sides. The formula for finding the area of a rectangle is:
Area = length x width
For example, if the length of a rectangle is 5 units and it's width is 3 units, it's area can be calculated by:
Area = 5 x 3 = 15 square units
Another example, if the length of a rectangle is 100 units and the width is 40 units, the area of the rectangle is:
Area = 100 x 40 = 4000 square units
So, to calculate the area of a rectangle, simply multiply its length (longer side) by its width (shorter side).
