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