Question

The Formula for the area of a trapezoid is A=1/2(b1+b2)h when this equation is solve for B1, One equation is b1=2A/h -b2 which of the following is an equivalent equation to find b1

Answer 1

A

Step-by-step explanation

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

Answer 2

see below

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
