Answer: The answer is 62 ft.
Step-by-step explanation:
To find the perimeter, you do 2 times the width and 2 times the length. 3 times 2 equals 6 and 28 times 2 equals 56. 6+56=62
((5x2)+5.5+(6x3)+6.5+(7x5)+(7.5x4)+(8x4))/20
137/20
= 6.85
Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.

I feel like it’s the last set but then again I haven’t done that kind of math in a few years. Hopefully that helps !
