Question

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches. What are the dimensions

of the rectangle?
Which of the following equations could be used to solve the problem?
2x+ 2 x - 3 = 54
0 2x+ 2(x-3) = 54
02x-3= 54

Answer 1

2(x-3)+2x=54

Explanation:

Take the side length of the rectangle as x

For the perimeter we must have - as we also have 2 lots of a side that is 3 inches shorter than x.

`2x + 2(x-3) = 54`
