Answer:

44.8 square yards

Step-by-step explanation:

Area of trapezoid:

     a = 7.8 yds

     b = 5 yds

    h =  7 yds

    [tex]\sf \boxed{\bf Area \ of \ trapezoid = \dfrac{(a +b)*h}{2}}[/tex]

Here, a and b are the parallel lines and h is the height between the parallel lines.

                                        [tex]\sf = \dfrac{(7.8+5)*7}{2}\\\\= \dfrac{12.8*7}{2}\\\\=6.4*7\\\\=44.8 \ square \ yards[/tex]
