Question

the area of a trapezoid is given by the equation A=n/2(a+b) find the area with of a trapezoid with base A=n/2(a=b)

Answer 1

A.  b1 = (2A -b2h)/h

Step-by-step explanation:

Multiply by 2 and expand the right side

2A = b1h +b2h

Subtract the b2 term

2A -b2h = b1h

Divide by h

b1 = (2A -b2h)/h
