Question

Alg. 1 question, I will mark brainliest for the best/first answer!

Answer 1

Answer:

A

Step-by-step explanation:

Let the two sides of the rectangle be x and y.

Then the perimeter will be:

$2x+2y=P$

Since the perimeter is 54:

$2x+2y=54$

We know that one side of the rectangle is 3 inches shorter than the other.

Let y be the shorter side. It is 3 less than x.

Therefore:

$y=x-3$

Then by substitution, we acquire:

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

The answer is A.
