Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 15) + (4 x 3) + (4 x 4)
= 60 + 12 + 16
= 88 cm
(b)
Length of AB
= 15 - 4 - 4
= 7 cm
Length of CD
= 15 - 3 - 3
= 9 cm
Area of the figure
= (15 x 15) - (2 x (7 x 3)) - (2 x (9 x 4))
= 225 - 42 - 72
= 111 cm
2 Answer(s): (a) 88 cm; (b) 111 cm
