Question

A rectangle has a perimeter of 45 ft. The length and width are scaled by a factor of 1.5.

What is the perimeter of the resulting rectangle?



Enter your answer in the box.

Answer 1

Perimeter is the sum of the 4 sides. If the sides are scaled by a factor of 1.5, then the perimeter is also scaled by a factor of 1.5.

New perimeter: 45 ft x 1.5 = 67.5 feet.
