Okay, here we have this:
Considering the provided information, and measures, we are going to calculate the requested amount of fencing anf the area, so we obtain the following:
Where the amount that she needs to fence corresponds to the perimeter, therefore it will be:
Perimeter=122 ft+ 215 ft+ 192.525 ft
Perimeter=529.525 ft
She needs 529.525 ft to fence the ground.
And the area of the land is:
Area=absin(c)/2=193.525(122)sin(83°)/2
Area=11,656.5 ft^2
Finally we obtain that
