I'm not sure what level of math you are at, so I hope it's alright that I used the trig function of tangent. Basically, you just have to find the second base to be able to find the area using the formula for the area of a trapezoid (A = ½h(b₁ + b₂)). To do this, use the information given and a little creativity to create a triangle and find the missing pieces. Finally, plug everything into the equation and voilà. Hope that helps!
