Question

If the rectangle below is enlarged by a scale factor of 2, what will be the perimeter of the new rectangle?

A rectangle is drawn with a length of 5 units and a width of 3 units.

Answer 1

Answer: 32

Explanation:

The scale factor is 2, which means you need to multiply the length and width by 2. So, 5 will become 10 and 3 will become 6, and you can find the perimeter by using 2L+2R, which is 32.

Alternatively...

The perimeter of the original figure is 16, and since the scale factor is 2, you multiply the perimeter by 2 and 16x2=32.
