A rectangle has a length of 8ft and a width of 6ft. if its length and width increase by 50% each, what is the area of the new rectangle? please help its due today at 2!!

108 ft²

Step-by-step explanation:

Increasing by 50% means multiplying the original quantities by 1.5, that is

100% + 50% = 150% = 1.5 ( 100% is the original dimensions ), thus

new length = 1.5 × 8 ft = 12 ft

new width = 1.5 × 6 ft = 9 ft

Thus

Area = length × width = 12 × 9 = 108 ft²

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
