Answer:
Step-by-step explanation:
[tex]S = \frac{n}{2} (a+l)\\2s = h(a+l)\\2s = ha +hl\\\frac{2s}{a+l} = h+h\\2h = \frac{2s}{a+l}\\h = (\frac{2s}{a+l})/2\\h = \frac{2s}{2a+2l}[/tex]
To Make h subject of the formula
Step 1
: Cross multiply
Step 2 :
Use h to open the bracket
Step 3 :
Divide both sides by a +l to make h on one side of the equation
Step 4 :
Evaluate h+h = 2h
Divide both sides of the equation by 2
