Answer: B 386
Step-by-step explanation:
(7*15)*2 + (7*4)*2 + (15*4)*2
= 210+120+56
= 386
The area of a circle is pi • radius^2
so
3.4^2 • 3.14 = 36.3
Good luck! The answer is C!
Answer:
8- 3x = 2 I think this is
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
