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 4)
= 64 + 12 + 16
= 92 cm
(b)
Length of AB
= 16 - 4 - 4
= 8 cm
Length of CD
= 16 - 3 - 3
= 10 cm
Area of the figure
= (16 x 16) - (2 x (8 x 3)) - (2 x (10 x 4))
= 256 - 48 - 80
= 128 cm
2 Answer(s): (a) 92 cm; (b) 128 cm
