Scott made a casserole for dinner. He gave equal portions of the casserole to 3 friends. What diagram could Scott use to find the fraction of the whole casserole that each friend got?

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

is only a line? i think so
