How to find the area of a rectangle?
The area of a rectangle can be calculated by multiplying its length by its width. The formula for the area of a rectangle is:
Area = length x width
A = l x w
where “A” represents the area, “l” represents the length, and “w” represents the width.
For example, if a rectangle has a length of 5 units and a width of 3 units, then its area can be calculated as:
A = 5 x 3 = 15 square units
So, the area of the rectangle is 15 square units.
How to find an unknown side?
You can use division to find the unknown side length of a rectangle when given the area and a side.
For example, if a rectangle has a width of 3 units and an area of 15 square units, then the length of its unknown side is:
15 ÷ 3 = 5 units
So, the length of the rectangle is 5 units.
