108 cm^2

Explanation:

rectangle + 2 triangle = total area

L x W + 2 * 1/2 base * height = total area

(5x12) + 2 * 1/2 * 12 * 4 = total area

60 + 48 = 108 cm^2

Explanation:

To do:

1. find area of rectangle 2. find area of triangles 3. add them together

area of a rectangle = bxh = 5x12 = 60

area of triangle = (bxh)/2 = (12x4)/2 = 24
