Question

Solve for L: A = L • W • H Choices: A) L = AW / H
B) L = WH / A
C) L = A / WH
D) L = W / HA:

Answer 1

We will divide both sides by WH:
A = L · W · H   /  : WH
L = A/ W H
Answer:C )

Answer 2

Step  1  : l Simplify — a Equation at the end of step  1  : l — - lwh = 0 a Step  2  :Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction 

Rewrite the whole as a fraction using  a  as the denominator :

lwh lwh • a lwh = ——— = ———————             1 a   L (liter) : A = 1 H L W (henry liter watt)
A = L · W · H   /  : WH
L = A/ W H so c is the answer
