Make p the subject of the relation A is equal to 1/2 ( p + b) h​

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p

Step-by-step explanation:

A = 1/2 ( p+b)h

Multiply each side by 2

2A =  ( p+b)h

Divide by h

2A/h =  ( p+b)h/h

2A/h =  ( p+b)

Subtract b

2A/h   -b =   p+b -b

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p
