Answer:
triangles: 28 cm^2 rectangle: 70 cm^2 trapezoid: 98cm^2
Step-by-step explanation:
The formula for the area of a triangle is base x height x 1/2.
Plug in the dimensions; 4 x 7 x 1/2 = 28 x 1/2 = 14 cm ^2 Since there are 2 triangles, you need to multiply the are of the triangle by 2. This becomes a total of 28 cm^2
The formula for the area of a rectangle is length x width.
Plug it in; 7 x 10 = 70 cm^2
To find the trapezoid's area, just add the two areas, giving you 98 cm^
