Area of the tarp which is in the shape of trapezium is 660sq.ft.
We have been given that a tarp which is in the shape of a trapezium covers the grass on part of a baseball field. We have to find the area of the trapezium.
The formula of area of trapezium is given as :
                A = 1/2* (Sum of parallel sides) * (Height)
            Or,  A = 1/2*(a+b)*h       (1)
                      Where a and b denote the parallel sides and h denote the height of the trapezium.
According to the figure given below,
    Let a = 24ft  ,   b = 64ft,   h = 15ft
Now putting these value in equation (1) we get,
 A = 1/2*(24+64)*15sq.ft
A = 1/2*88*15sq.ft
A = 660sq.ft
Thus the area of the trapezium is 660sq.ft
