There are 1 rectangle and 2 triangles. The area of the rectangle is 5 x 7 =35 The are of the triangle is 7 x 2 = 14(1/2) = 7 There are 2 triangles, so 7 x 2 = 14
The area is 49 because the formula for finding the area of trapezoid is A= ((a+b)/2)h. Basically, you add the top and bottom bases and divide it by 2 then multiply it by the height.
