Answer:

27-28

x^2+3x-180 = 0

29-30

C. length = 15m and width = 12 m

Step-by-step explanation:

27-28

width = x

length = x+3

length × width = Area

(x+3)(x) = 180

x^2+3x = 180

x^2+3x-180 = 0

29-30

x^2+3x-180 = 0

(x+15)(x-12) = 0

x+15 = 0 => x = -15 (not possible)

x-12 = 0 => x = 12

length = x+3 = 12+3 = 15 m

width = x = 12 m

C. length = 15m and width = 12 m
