In similar figures sides are in proportion

The sides of the bigger parallelogram are x+8 and 20

The sides of smaller parallelogram are x and 12

The sides are in proportion

(x+8)/(x) =(20)/(12)

We can solve this for x

To solve for x we cross multiply

20x=12(x+8)

20x=12x+96

Subtracting 12x both sides

20x-12x=96

8x=96

Dividing both sides by 8

x=12
