simple math question...

[kenso]

i was taking the ACT earlier today, and for the life of me i got stumped on a very simple math question. someone remind me how to break this one down -

you have a rectangle with an area of 162 square yards, what is the perimeter of the rectangle if the length is twice the width.

a formula would be nice.

Solve

2X squared = 162

Answer X = 9

so width = 9 yards and length = 18 yards
