A town is planning a new rectangular park. The park will have a length equal to twice it's width. A sidewalk 2 meters wide will surround the park. The area of the park and sidewalk is given in the formula A= 2x(to the power of 2) +12x+16. In the formula x is the width of the park. The park is 70 meters wide. What is the total area of the park and sidewalk. Show your steps.

What is the total area of the park and sidewalk. Show your steps.
So we have
2(70)^2 + 12(70) + 16 = 10656m^2 and that's the total area of the park and the sidewalk
The park's width, without the sidewalk, is just 66 and the length is twice that = 132.
So, the area of the park, not icluding the sidewalk is just 66 x 132 = 8712m^2
So the area of the sidewalk is the difference between the above = 10656 - 8712 = 1944m^2
