Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 17) + (4 x 2) + (4 x 4)
= 68 + 8 + 16
= 92 cm
(b)
Length of AB
= 17 - 4 - 4
= 9 cm
Length of CD
= 17 - 2 - 2
= 13 cm
Area of the figure
= (17 x 17) - (2 x (9 x 2)) - (2 x (13 x 4))
= 289 - 36 - 104
= 149 cm
2 Answer(s): (a) 92 cm; (b) 149 cm
