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 4)
= 64 + 8 + 16
= 88 cm
(b)
Length of AB
= 16 - 4 - 4
= 8 cm
Length of CD
= 16 - 2 - 2
= 12 cm
Area of the figure
= (16 x 16) - (2 x (8 x 2)) - (2 x (12 x 4))
= 256 - 32 - 96
= 128 cm
2 Answer(s): (a) 88 cm; (b) 128 cm
