Area of a Pentagon | Problem Solving

In this video, Mr. Moussally solves a pretty easy problem involving a pentagon consisting of 6 isosceles triangles. There are two methods to solve this problem, method one is to find the area of one triangle by using the formula (0.5 x a x b x sin c) then multiplying by 6 (as there are 6 of the same triangles). The second method is to find the height of one of the triangles then finding the area using the formula (b x h x 0.5) then multiplying by 6 (as there are 6 of the same triangles).
