Answer:
75
Step-by-step explanation:
75m/hr
Let:
L = Length
W = Width
The length is 7cm longer than its width, so:
The area is given by:
Therefore:
Solve for W using the quadratic formula:
Therefore:
W = 12.38238 since a negative width wouldn't make any sense
and:
Answer:
W = 12.38238 m
L = 19.38238 m
6.5 is the answer. You can check by 6.5x8=52
