One rectangle has a length of 4x+2 and a width of 2x. A square has side lengths that are 4x. If the perimeter of the rectangle and the square are equal, what are the dimensions of the square?

Side lengths are 2

Step-by-step explanation:

Perimeter of the rectangle would be = 4x+2+4x+2

Simplified= 8x +4

Perimeter of the square=4x+4x+4x+4x

Simplified 16x

16x=8x+4

Take away 8x

8x=4

Then divide by 8

X=0.5

The squares side lengths are 4x, so 0.5 times 4 is 2.

Hi!

Assuming the 9in is the radius, we would multiply it by 2, or add it to itself. We then get 18 in.

Hope this helps!
