Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (53 + (5 x 13) + 15 + 46)
= 2 x (53 + 65 + 15 + 46)
= 2 x 179
= 358 cm
(b)
Area of the figure
= (2 x 53 x 13) + (2 x 7 x 13) + (22 x 13)
= (2 x 689) + (2 x 91) + 286
= 1378 + 182 + 286
= 1846 cm
2 Answer(s): (a) 358 cm; (b) 1846 cm
