The equation is


B) Solve your equation in part [A] to find the width of the rectangle.

Answer: The rectangle is
cm wide.

Answer 1

Explanation:

A) The equation for the perimeter of a rectangle is given by 2 * (length + width), so we can write the equation for this rectangle as:

2 * (30 + w) = 108

B) To find the width of the rectangle, we can solve for w:

60 + 2w = 108

2w = 48

w = 24

So, the width of the rectangle is 24 cm.
