Answer:
20 meters
Step-by-step explanation:
Area = Length * Width
4 = x * 0.2
4/0.2 = x
x = 20 meters
Answer:
x2 - x - 12 = 0
Step-by-step explanation:
(x - 4) (x + 3) = 0
x(x + 3) -4(x + 3) = 0
x2 + 3x -4x - 12 = 0
x2 -x -12 = 0
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A
B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
