Area of Squares and Rectangles: Word Problems

The area is the amount of surface enclosed by a closed figure.

Area of a rectangle = length × width

Area of a square = side × side

 

For example, consider this situation.

The area of a rectangular pool is 500 square feet. The width of the pool is 20 feet.

Let's find the length of the pool.

 

1


We know,

 

Length  ×  width  =  area
Length  ×  20  =  500 
    Length  = 500 ÷ 20
       = 25 

 

So, the length of the pool is 25 feet.
