Question

40 POINTS!!! A square has a perimeter of 28 cm. All dimensions are increased by a scale factor of 3 to create a similar figure.What is the area of the new figure?

Answer 1

The area of the new figure:

= 441 cm^2

Explanation:

A square has a perimeter of 28 cm, so each side = 28/4 = 7 cm

All dimensions are increased by a scale factor of 3, so new dimensions of side will be 7 x 3 = 21 cm

The area of the new figure:

Area = (21)^2 = 441 cm^2
