Answer:
The width is 12 m and the length is 14 m
Step-by-step explanation:
Let w = width
l = w+2
A = l*w
168 = (w+2) * w
Distribute
168 = w^2 +2w
Subtract 168
0 = w^2 +2w -168
Factor
0 = (w-12)(w+14)
Using the zero product property
w-12 =0 w+14 =0
w=12 w=-14
Since we cannot have a negative width
w=12
l = w+2 = 12+2 = 14
Answer:
The length is 14 meters and the width is 12 meters
Step-by-step explanation:
14 times 12 = 168
14 - 12 = 2
