Mr. fry is building a fence around his pool.

•length of the fence is 60 feet.
•width of the fence is 30 feet.

how many yards of fence will mr. fry build?
a) 30 yards
b) 60 yards
c) 90 yards
d) 540 yards

Add the two to each other twice, and add the sum

(30+60) + (30+60) = 180 ft

Then divide by three for yards.

The answer is choice B.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
