Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 16) + (4 x 3) + (4 x 5)
= 64 + 12 + 20
= 96 cm
(b)
Length of AB
= 16 - 5 - 5
= 6 cm
Length of CD
= 16 - 3 - 3
= 10 cm
Area of the figure
= (16 x 16) - (2 x (6 x 3)) - (2 x (10 x 5))
= 256 - 36 - 100
= 120 cm
2 Answer(s): (a) 96 cm; (b) 120 cm
