    This 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.

    or you could use Heron's formula

    s=(a+b+c)/2 Area = (s(s-a)(s-b)(s-c))^(1/2)
