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 3)
= 56 + 8 + 12
= 76 cm
(b)
Length of AB
= 14 - 3 - 3
= 8 cm
Length of CD
= 14 - 2 - 2
= 10 cm
Area of the figure
= (14 x 14) - (2 x (8 x 2)) - (2 x (10 x 3))
= 196 - 32 - 60
= 104 cm
2 Answer(s): (a) 76 cm; (b) 104 cm
