ANSWER
61.8 m^[2].
We first examine what we have which is:
A parallelogram with base 14m and height 8m
A circle with DIAMETER 8m
Given our area formulas, we know we have our b and h in our parallelogram formula given. If our circle diameter is 8m, our circle radius must be 4m. Therefore, we have every element of our formulas we need.
parallelogram area = b*h = 14*8 = 112m^[2]
circle area = pi*r^[2] = pi*4m^[2]=16*3.14=50.24m^[2].
now we just subtract our circle area from our parallelogram area, and round our answer to the nearest tenth (the first place to the right of the decimal):
112m^[2]-50.24m^[2]=61.76 m^[2].
Rounded to the nearest tenth, this number becomes 61.8 m^[2].
