A rectangular garden, with length twice its width, is to be expanded so that each side is increased by 4 yards.
a. Write expressions for the dimensions of the expanded garden.
b. Write and simplify an expression to represent the area of the expanded garden.

If x = width, then 2x = length.
a. (x+4) by (2x+4)
b. (x+4)(2x+4)= Area
I'll let you simplify it.
