Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (60 + (5 x 18) + 13 + 53)
= 2 x (60 + 90 + 13 + 53)
= 2 x 216
= 432 cm
(b)
Area of the figure
= (2 x 60 x 18) + (2 x 7 x 18) + (20 x 18)
= (2 x 1080) + (2 x 126) + 360
= 2160 + 252 + 360
= 2772 cm
2 Answer(s): (a) 432 cm; (b) 2772 cm
