It shows the Ora scale for area multiply width and length
Answer: The first situation fit the equation and it will take Mitch 4.5 weeks to pay back
Step-by-step explanation:
Answer:
700 foundations is the answer
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
