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
2x + 2x - 3 = 54
2x - 3 = 54

Answer 1

c is the correct answer

Answer 2

Thank you for asking this question. Here is your answer:

The shorter sides of the rectangle can be t inches

And we can assume the longer sides to be t+3 inches

now we will calculate the perimeter:

2t + 2(t+3)

= 4t + 6

4t + 6 = 54

Now we will do the subtraction ( from both sides 6 will be subtracted)

4t = 48

and now we will divide 4 by both sides:

t = 12

So that means the shorter sides are 12 inches and longer sides are 12 + 3 = 15 inches is the final answer.
