A = 1/2h(B + b)
2(A = 1/2h(B + b)
2A=h(B+b)
2A/h=B+b
2A/h-B=b

Given A = 1/2h(B + b)
==> A = h/2(B+b)
==> 2A = h(B+b) [ multiplying both the sides by 2]
==> 2A/h = B + b [Dividing both the sides by h]
==> 2A/h - B = b [Adding -B to both the sides]
==> (2A - Bh)/h = b [Taking h as the common denominator for the left hnd side]
