Question

The formula for finding the perimeter of a rectangle with length, l, and width, w, is P = 2l + 2w.

If the length and width of a rectangle are both doubled, how is the perimeter affected?


A. The perimeter remains the same.
B. The perimeter is multiplied by 1/2
C. The perimeter is twice as great.
D. The perimeter is four times as great.

Answer 1

D) The perimeter would be four times larger if the sides became longer because the perimeter is how long the rectangle is all the way around. If you take each side and make it longer than the perimeter would be four times as great because there is four sides that is getting longer.
I hope this helps!

Answer 2

the perimeter would be C. twice as great
