HELP!!! Math

The area of a yard is 15000 ft^2. If the ratio of the lenght to the width of the yard is 3:2, what are the dimensions of the yard?

Width = X Ft.
Length = 3X/2 Ft.
Area = (3x/2) * X = 15,000 Ft^2
Multiply both sides by 2:
3x * x = 30.000
3x^2 = 30000
x^2 = 10000
X = 100 Ft^2.
3x/2 = (3*100)/2 = 150 Ft^2
