Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 14) + (4 x 3) + (4 x 4)
= 56 + 12 + 16
= 84 cm
(b)
Length of AB
= 14 - 4 - 4
= 6 cm
Length of CD
= 14 - 3 - 3
= 8 cm
Area of the figure
= (14 x 14) - (2 x (6 x 3)) - (2 x (8 x 4))
= 196 - 36 - 64
= 96 cm
2 Answer(s): (a) 84 cm; (b) 96 cm
