Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 13) + 12 + 45)
= 2 x (51 + 65 + 12 + 45)
= 2 x 173
= 346 cm
(b)
Area of the figure
= (2 x 51 x 13) + (2 x 6 x 13) + (18 x 13)
= (2 x 663) + (2 x 78) + 234
= 1326 + 156 + 234
= 1716 cm
2 Answer(s): (a) 346 cm; (b) 1716 cm
