Question

A rectangle has a perimeter of 48 ft. The length and width are scaled by a factor 1.5.

What is the perimeter of the resulting rectangle?

Answer 1

A scale factor is the ratio of two similar geometric figures of their corresponding sides. The scale factor is calculated by locating the corresponding sides on each figure. We calculate as follows:

1.5 = P2/P1
P2 = 1.5(48) = 72 ft

Hope this answers the question. Have a nice day.
