PROBLEM 1: The formula for the area of the hexagon is attached below.
Plug in the number 4 for letter A and solve.
The area of the hexagon is 41.57. Once rounded to the nearest tenth it's 41.60
PROBLEM 2: Perimeter = Number of sides x length of side
54 = 18 x length, length = 3m
Area = L^2 * N divided by 4Tan(π / N), L=3 and N=18
Area = 3^2 x 18 divided by 4(0.176399)
Area =299.59m^2
Rounded to the nearest tenth it's 299.60.
Hope that helps! -UF aka Nadia
