To find the length of each side of the trapezoid, you need to use the distance formula. AB = (-3,2) and (1,5) BC = (1,5) and (7,-3) CD = (7, -3) and (0, -2) AD or DA = (0,-2) and (-3,2) Now, just use the distance formula for each line. Doing so gives us: AB = 5 BC = 10 CD = 7.071107... DA or AD = 5 The height is AB, the first base is BC and the second base is CD. We can plug the values for these sides into the trapezoid area formula, which is A = base 1 + base 2 all over 2 times the height. Doing so gives us 37.5 units². Therefore, the answer to your query is 37.5 units². Hope this helps and have a nice day!
