Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 12) + 16 + 45)
= 2 x (51 + 60 + 16 + 45)
= 2 x 172
= 344 cm
(b)
Area of the figure
= (2 x 51 x 12) + (2 x 6 x 12) + (22 x 12)
= (2 x 612) + (2 x 72) + 264
= 1224 + 144 + 264
= 1632 cm
2 Answer(s): (a) 344 cm; (b) 1632 cm
