Answer
The width is 12 cm and the length is 34 cm.
Work Step by Step
Since the length is stated in terms of the width, we can let w represent the width.
Since the length is 2 less than three times the width, or w, the length is equal to 3w - 2.
The formula for the perimeter of the rectangle is width + width + length + length
The perimeter of the rectangle is 92, so we set up the following equation:
w + w + 3w - 2 + 3w - 2 = 92
8w - 4 = 92
Add 4 to both sides.
8w = 96
Divide both sides by 8.
w = 12
Since w = 12, the length is equal to 3 $\times$ 12 - 2 = 34.
