As shown, a baseball's stadium playing field is shaped like a pentagon. To find the area of the playing field shown at the right, you can divide the field into two smaller polygons.

Find the area of the playing field in square feet. Round to the nearest square foot. Then express your answer in sq. yards.

Solution:

S = S1+S2

S1 = 0.5*(145+450)*179 = 53252.5

S2 = 0.5*315*322 = 50715

So

S = 53252.5+50715 = 103,968

So the area of the playing field is 103,968 square feet
