Question

SOMEBODY PLEASE HELP ME!!!!

Answer 1

So the perimeter of the larger rectangle = 160

Explanation:

We are given the scale factor of the two rectangles. We are given the perimeter of the smaller rectangle = 120.

Since the two rectangles are scaled, this means they have a common ratio. In other words:

`(perimeter \: of \: larger \: rectangle)/(perimeter \: of \: smaller \: rectangle) = (4)/(3)`

As given in the question.

Now we know the smaller rectangle has a perimeter of 120.

Let's take the perimeter of the larger rectangles as x.

`(x)/(120) = (4)/(3) \\ \\ multiplying \: both \: sides \: by \: 120 \\ x = (4)/(3) (120) \\ x = 160`

So the perimeter of the larger rectangle = 160
