solve for b: p=1/2h(a+b)
-
dividing 1/2 is like multiplying by 2 so mult both sides by 2:
2p = h(a+b)
divide h by both sides:
2p/h = a+b
subtract a from both sides:
2p/h - a = b
2p = h(a+b)
divide h by both sides:
2p/h = a+b
subtract a from both sides:
2p/h - a = b

Will assume that question SHOULD read as :-
p = (1/2) ( h ) ( a + b ) and NOT as given.
2p / h = a + b
b = ( 2p / h ) - a
p = (1/2) ( h ) ( a + b ) and NOT as given.
2p / h = a + b
b = ( 2p / h ) - a
-
p/"1/2h"-a=b
Divide both sides by "1/2h" and then subtract a from both sides. Thats how you get the above answer
Divide both sides by "1/2h" and then subtract a from both sides. Thats how you get the above answer
