Question

Find the area of the composite shape below.

a 66.8
b 91.92
c 101.12
d 101.6

Answer 1

Area of figure= area of triangle+ area of rectangle
= 1/2*4.4*7.8+2.8*11.4
= 17.16+31.92
= 49.08 square units

Answer 2

66.24 (This answer does not match to any of the options...)

Explanation:

This shape can be divided into 2 different shapes. A triangle and a rectangle.

Area of a Triangle =
`(1)/(2)` × base × height

=
`(1)/(2)` × 8.8 × 7.8

= 34.32

Area of a Rectangle = Length × Width

= (19.2 - 7.8) × (8.8 - (3+3))

= 11.4 × 2.8

= 31.92

Total area = 34.32 + 31.92 = 66.24
