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 twice the size of the existing ones. How will this change affect the perimeter of the sun roof?

Answer 1

The perimeter of a rectangle = 2(l +w )
When you increase the size of the length and width it would be 2(2l+2w)

Lets assign values to l and w where l>w

l=4
l=2
The original roof would have a perimeter of 2(4+2)= 12
Doubling the l and w would give us 2(4(2)+(2)2)= 2(8+4) =24
From this we can conclude that the perimeter doubled

Answer 2
