Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
Hello!
To find the area of a hexagon you do 3

where a is one of the sides
Since the perimeter is 60 we can do 60/ the sides of the shape
60/6 = 10
So one side is equal to 10
you put that into the formula to get the area of a hexagon and you get 259.81
Hope this helps!
