Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 17) + (4 x 3) + (4 x 5)
= 68 + 12 + 20
= 100 cm
(b)
Length of AB
= 17 - 5 - 5
= 7 cm
Length of CD
= 17 - 3 - 3
= 11 cm
Area of the figure
= (17 x 17) - (2 x (7 x 3)) - (2 x (11 x 5))
= 289 - 42 - 110
= 137 cm
2 Answer(s): (a) 100 cm; (b) 137 cm
