The trapezoid is composed of a rectangle and two triangles. what is the area of the rectangle? what is the total area of the triangles? what is the area of the trapezoid? a) 34 cm2; 28 cm2; 62 cm 2 b) 34 cm2; 14 cm2; 48 cm 2 c) 70 cm2; 28 cm2; 98 cm 2 d) 70 cm2; 14 cm2; 84 cm 2

Area of a rectangle is L * W
so the area of this rectangle is : 7 * 10 = 70 cm^2

area of a triangle is (height * base) / 2
so the area of 1 triangle is : (7 * 4) / 2 = 28/2 = 14 cm^2...but u have 2 of themso the total area of the triangles is 2(14) = 28 cm^2

so ur trapazoid has a total area of : 70 + 28 = 98 cm^2

ur answer is : C
