The width of a rectangle measures left bracket, 7, h, plus, 3, right bracket(7h+3) centimeters, and its length measures left bracket, 8, h, minus, 4, right bracket(8h−4) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

The perimeter of a rectangle is given by the formula P=2(length + width).
The expression for the width is (7h+3) centimeters.
The expression for the length is (8h−4) centimeters.
Therefore, the perimeter is equal to:
P = 2[(7h+3) + (8h−4)]
Simplifying this expression, we get:
P = 2[15h - 1]
P = 30h - 2 centimeters.
So, the expression that represents the perimeter of the rectangle is 30h - 2.
