**Ms. Sue**, Wednesday, November 14, 2012 at 12:25pmOne way to figure it out is to let x = the actual width. Cross multiply and solve for x.

(1/2) / 10 = (3/4) / x

30/4 = (1/2)x

(30/4)/(1/2) = x

(30/4) * (2/1) = 60/4 = 15 feet

**Ms. Sue**, Wednesday, November 14, 2012 at 1:59pmHere's another way to approach this problem.

1/2 inch = 10 ft.

1 inch = 20 ft.

3/4 * 20 = 15 feet

I'm retired.
