Question

A 3" × 5" rectangle is dilated by a scale factor of 2. what will its new perimeter be?​

Answer 1

The new perimeter is going to be 32”

When u dilate a rectangle by a scale factor of two, each side measurement is multiplied by 2, therefore the new rectangle is a 6” X 10”

Because it is a rectangle that means 2 sides are 6” and 2 other sides are 10” so you would add 10+10+6+6 which gets u 32.

Answer 2

Answer:

6" × 10"

Step-by-step explanation:

Because the dilation is a whole number we know the rectangle will be enlarging, and we are told this is by two. So you will take and multiply the dimensions by two.

(2 × 3") × (2 × 5")
