Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (57 + (5 x 12) + 18 + 52)
= 2 x (57 + 60 + 18 + 52)
= 2 x 187
= 374 cm
(b)
Area of the figure
= (2 x 57 x 12) + (2 x 5 x 12) + (23 x 12)
= (2 x 684) + (2 x 60) + 276
= 1368 + 120 + 276
= 1764 cm
2 Answer(s): (a) 374 cm; (b) 1764 cm
