Question

Find the perimeter and area of the image after dilating the figure shown with the given scale factor.

Answer 1

Im pretty sure it’s:

p’ = 12(5)=60

a’ = 9(5^2)=225

you probably don’t have to include the equation, but i wanted to put it in there just in case :-)

Answer 2

When asking for you to change to scale factor, it means that the shape is going to be 5x the shape, therefore, simply multiply the perimeter and area by 5, P = 60 A = 45
