Okay, so you are trying to find the total of the basement. Your formula is (L2 + W2). So your length is 35ft. Your W is 28ft. So 35+35= 70ft and 28+28= 56ft. Now 70ft + 56ft is 126ft. 126 is your total
I cant really attach a picture but this is the answer so you turn 2 1/2 into a improper fraction which is 5/2. then you multiply 11/3*5/2. And that equals 55/6. and then turn it into a whole number and it equals 9.16..
