Answer 1

it's 9in

Step-by-step explanation: i got it right on my test

Answer 2

P = 48 in²

Explanation:

Given: A rectangle; Width = 9 inches, length = 15 inches, enlarged by a scale factor of
`(3)/(2)`

To find: Perimeter of the dilated rectangle

Formula:
`P=2(l+w)`

Solution: After a dilation with a scale factor of one-half, then the lengths on the image would be one-half , one-half , and one-half . To find the perimeter of an enlarged figure, you can multiply the original figure's perimeter by the scale factor.

`P=2(l+w)=2` ×
`(15+9)=48in`

Therefore, the perimeter of the detailed rectangle that was enlarged is 48 in²
