Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 15) + (4 x 4) + (4 x 6)
= 60 + 16 + 24
= 100 cm
(b)
Length of AB
= 15 - 6 - 6
= 3 cm
Length of CD
= 15 - 4 - 4
= 7 cm
Area of the figure
= (15 x 15) - (2 x (3 x 4)) - (2 x (7 x 6))
= 225 - 24 - 84
= 117 cm
2 Answer(s): (a) 100 cm; (b) 117 cm
