Question

make h the subject A=1/2(a+c)h​

Answer 1

Answer:

h = $\frac{2A}{a+c}$

Step-by-step explanation:

Given

A = $\frac{1}{2}$(a + c)h

Multiply both sides by 2 to clear the fraction

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

$\frac{2A}{a+c}$ = h

Answer 2

Answer:

[see below]

Step-by-step explanation:

$a = 1/2(a+c)h\\\\1/2(a+c)h = a\\\\2 * 1/2(a+c)h = a * 2\\\\h(a+c)=2a\\\\\frac{h(a+c)}{a+c}=\frac{2a}{a+c}; a \neq -c\\\\\boxed{h=\frac{2a}{a+c}; a \neq -c}$

Hope this helps.
