Question

The sun roof in Troy’s house is shaped like a rectangle. He increases the length of the sides of the sun roof to four times the existing ones. How will this change affect the perimeter of the sun roof?

Answer 1

P=2b+2h
if b and h are multiplied by 4, our new perimeter S is:
S=2(4b)+2(4h)=4(2b+2h)=4P
So our new perimeter will be 4 times as big as the old one.
