The third answer (Dividing the area by the height, multiplying the quotient, etc) is correct.
If we multiply by the height, we receive an expression equal to the sum of the bases divided by two. Multiplying by two, we now have the sum of the bases. Subtracting one base gives the length of the other base.
To express (32+56) as a multiple sum of whole number we proceed as follows; 32=2*2*2*2*2=2^5 56=2*2*2*5=(2^3)*5 Thus; (32+56) =2^5+2^3*5 =2^3(2^2+5) The answer is: 2^3(2^2+5)
