Question

Make h the subject A=1/2(a+c)h​

Answer 1

[see below]

Explanation:

`a = 1/2(a+c)h\\\\1/2(a+c)h = a\\\\2 * 1/2(a+c)h = a * 2\\\\h(a+c)=2a\\\\(h(a+c))/(a+c)=(2a)/(a+c); a \\eq -c\\\\\boxed{h=(2a)/(a+c); a \\eq -c}`

Hope this helps.

Answer 2

h =
`(2A)/(a+c)`

Explanation:

Given

A =
`(1)/(2)`(a + c)h

Multiply both sides by 2 to clear the fraction

2A = (a + c)h ( divide both sides by (a + c) )

`(2A)/(a+c)` = h
