Someone help fast!!! Easy points!!!

I couldn’t understand this it’s due tonight

Answer 1

2A/h - b2= b1

Explanation:

A = 1/2 ( b1+ b2) h

Multiply each side by 2

2*A = 2*1/2 ( b1+ b2) h

2A = ( b1+ b2) h

Divide each side by h

2A/h = ( b1+ b2) h/h

2A/h = ( b1+ b2)

Subtract b2 from each side

2A/h - b2= b1+ b2-b2

2A/h - b2= b1
