Answer:
10 ft, 14 ft
Step-by-step explanation:
Let b represent the length of the shorter base. Then the longer one is b+4 and the area is ...
A = (1/2)(b1 +b2)h
120 = (1/2)(b +(b+4))(10) . . . . use given values
12 = b+2 . . . . . . divide by 10, simplify
10 = b
14 = b+4
The measurements of the two bases are 10 ft and 14 ft.
