Answer:
Its width is 9.66 feet and length is 22.98 feet.
Step-by-step explanation:
Let l is length and b is width of a rectangular lot.
Length, l = (3b-6) feet
The area of the lot is 222 sq feet.
The area of a rectangle is given by :
[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]
It is a quadratic equation. The solution of the above equation is given by :
b = 9.66 feet and -7.66 feet
Neglecting negative answer, the width of the lot is 9.66 feet.
Length, l = (3(9.66)-6) = 22.98 feet
Hence, its width is 9.66 feet and length is 22.98 feet.
