    first of all, i don't know if there is a figure given in your question,, but if there is not, you have to imagine,,
    it is composed of a trapezoid EBCD and triangle AED,, therefore,
    Area,trapezoid = (b1+b2)*h/2
    Area,triangle = bh/2

    A,trap = (13+15)*18/2 = 252 sq yards
    A,tri = (20*15)/2 = 150 sq yards
    **note that 20 came from 38-18

    A,quad = 252+150 = 402 sq yards

    so there,, :)
