Answer:

33.75

Explanation:

We know that the perimeter is 90. The opposite side of 6x is 6x and the opposite side of 2x is 2x.

Combine like terms.

2x + 2x + 6x + 6x = 90

4x + 12x = 90

Divide both sides by 16.

16x = 90

----- ----

16 16

x = 5.625

Check:

Now we check to see if it adds up to 90 when we add them all together.

2(5.625) + 2(5.625) + 6(5.625) + 6(5.625) = 90

11.25 + 11.25 + 33.75 + 33.75 = 90

22.5 + 67.5 = 90

90 = 90
