Answer 1

The total area is 72 and A is the correct answer.

Explanation:

Here is how they used the formula in A:

60 = 5/6 x A (do 5/6 x A/1 = 5A/6)

60 =
`(5A)/(6)`(multiply both sides of the equation by 6 to get rid of the denominator)

60 x 6 =
`(5A)/(6)` x 6

360 = 5A (divide both sides of the equation by 5)

360 / 5 = 5A/5

72 = A
