Answer:
Area = 131.9167322
Step-by-step explanation:
I'm not sure what 2 DP means so you will need to do that part.
area=pi*radius^2
area=3.14*42 (approx)
With a square, all you need to do to find the length of one side is to divide the perimeter by 4. If it is the area you are calculating, then you need to find the square root. For that equation the answer is 24.
Try this option:
