Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (55 + (5 x 12) + 13 + 47)
= 2 x (55 + 60 + 13 + 47)
= 2 x 175
= 350 cm
(b)
Area of the figure
= (2 x 55 x 12) + (2 x 8 x 12) + (21 x 12)
= (2 x 660) + (2 x 96) + 252
= 1320 + 192 + 252
= 1764 cm
2 Answer(s): (a) 350 cm; (b) 1764 cm
