Answer 1

that was incorrect

Answer 2

The perimeter of a rectangle is the sum of all its sides. In this case, the perimeter would be the sum of the width (9p+7) and the length (p+10).

Therefore, the expression representing the perimeter would be:
(9p+7) + (p+10)

Simplifying this expression, we get:
10p + 17

So, the correct expression representing the perimeter of the rectangle is 10p + 17.

Answer 3

I apologize for the mistake. Let me re-evaluate the problem:

The formula for the perimeter of a rectangle is 2(length + width).

According to the given information, the width of the rectangle is (9p+7) centimeters and its length is (p+10) centimeters.

Therefore, the expression representing the perimeter would be:
2[(9p+7) + (p+10)]

Simplifying this expression, we get:
2(10p + 17)
= 20p + 34

So, the correct expression representing the perimeter of the rectangle is 20p + 34 centimeters.
