Best ResponseYou've already chosen the best response.0This is an isosceles triangle. So you can cut this triangle in half to get dw:1331333001972:dw then you can use the pythagorean theorem to find the height x x^2 + 9^2 = 24^2 x^2 + 81 = 576 x^2 = 576  81 x^2 = 495 x = sqrt(495) x = 22.248595 So the height is roughly 22.248595 This means that the area is then A = (bh)/2 = (18*22.248595)/2 = 200.237355 So the area is roughly 200.237355 square units.
