Find x. The rectangle width is 2ft with and Area =28 sq ft. x is the length. Can you help?

Answer 1

Hi Grace,

 

The formula for the area of a rectangle is

 

area = length X width

 

The width = 2ft and the area = 28 sq ft. The problem chooses to represent the length by the variable x.

So, we can write the above equation as

 

28 = x X 2

 

or

 

2x = 28

 

Divide both sides by 2.

 

We get x = 28/2 = 14

 

x = 14 ft
