The value of this expression is 16. In exponential problems you can multiply the base by the number of times the exponent is. In this case it would be: 2*2*2*2. Then just multiply and get the product of 16.
so the 3ft at the front and the 8ft at the back, you do 8-3 which is 5 which will be A and on the side, it is 8ft and since the corner angle is 4ft then B will be 8-4 which is 4
