First, you need to find the length of each of the bases of this trapezoid. YZ has length 5-2=3, while XW has length 8-1=7. The average of these is 5, meaning that since the height of this trapezoid is 5-1=4, the area is 4*5=20. Hope this helps!
1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand cross multiply because this is a proportion (1)(x) = (7.15)(1000) x = 7150 <=== Sophia got 7150 rand
