Question

The expression 1/2c b+c can be used to find the area of the trapezoid. What is the area of the trapezoid when a=6, b=5, and c=7

Answer 1

Yes but you have a point and you are wrong on this point but you have a valid reason for it and I am sure that the person would have a valid argument

Answer 2

To find the area of a trapezoid, use the formula A=(a+b)/2*h. So in this case, (6+5)/2*7 would equal 31.5
