13ft X 10ft = 130 ft squared (but you have 2 walls with these demensions) so in total its 260 ft squared.

11ft X 10ft = 110 ft squared (but you have 2 walls with these demensions) so in total its 220 ft squared.

In total, 260 + 220 = 480 ft. squared.


Set this equal to (2.5ft)(50ft)(X).

So 1.25X = 480

X=3.84
