Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 16) + (4 x 2) + (4 x 3)
= 64 + 8 + 12
= 84 cm
(b)
Length of AB
= 16 - 3 - 3
= 10 cm
Length of CD
= 16 - 2 - 2
= 12 cm
Area of the figure
= (16 x 16) - (2 x (10 x 2)) - (2 x (12 x 3))
= 256 - 40 - 72
= 144 cm
2 Answer(s): (a) 84 cm; (b) 144 cm
