Answer:
The total area is 72 and A is the correct answer.
Step-by-step explanation:
Here is how they used the formula in A:
60 = 5/6 x A (do 5/6 x A/1 = 5A/6)
60 = [tex]\frac{5A}{6}[/tex](multiply both sides of the equation by 6 to get rid of the denominator)
60 x 6 = [tex]\frac{5A}{6}[/tex] x 6
360 = 5A (divide both sides of the equation by 5)
360 / 5 = 5A/5
72 = A
