Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 14) + (4 x 2) + (4 x 4)
= 56 + 8 + 16
= 80 cm
(b)
Length of AB
= 14 - 4 - 4
= 6 cm
Length of CD
= 14 - 2 - 2
= 10 cm
Area of the figure
= (14 x 14) - (2 x (6 x 2)) - (2 x (10 x 4))
= 196 - 24 - 80
= 92 cm
2 Answer(s): (a) 80 cm; (b) 92 cm
