12. Multistep A farmer needs to buy fertilizer for two fields. One field is shaped like a trapezoid, and the other is shaped like a triangle. The
trapezoidal field has bases that are 35 and 48 yards and a height of
26 yards. The triangular field has the same height as the trapezoidal
field and a base of 39 yards. Each bag of fertilizer covers 150 square
yards. How many bags of fertilizer does the farmer need to buy?

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

its adding 5.5 each time
