Question

What is the total area of the following composite figure?



136.26 m 2
122.13 m 2
117.42 m 2
62.13 m 2

Answer 1

Step-by-step explanation:

there is a rectangle and an octagon within

area of rectangle = 8*9 = 72

there are 4 right angled triangles

area of one such triangle = .5 × 9 = 4.5

total area of triangles = 18

area of octagon = 72-18 = 54 m^2
