Question

The diagram below is a composite shape.

a. On the diagram, add lines that divide it up into smaller shapes and write in any
missing side lengths for each small shape.
b. Find the total area.

Answer 1

Explanation:

a)

the figure is divided into three smaller rectangles named A, B and C:

area of rectangle A = Length * breadth = 12 * 3 = 36 m²

area of rectangle B = length * breadth = 5 * 6 = 30 m²

area of rectangle C = length * breadth = 15 * 3 = 45 m²

b)

total area = area of rectangle A + area of rectangle B + area of rectangle C

= 36 + 30 + 45 = 111 m²
