Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 13) + 16 + 47)
= 2 x (54 + 65 + 16 + 47)
= 2 x 182
= 364 cm
(b)
Area of the figure
= (2 x 54 x 13) + (2 x 7 x 13) + (23 x 13)
= (2 x 702) + (2 x 91) + 299
= 1404 + 182 + 299
= 1885 cm
2 Answer(s): (a) 364 cm; (b) 1885 cm
