Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 13) + 15 + 46)
= 2 x (51 + 65 + 15 + 46)
= 2 x 177
= 354 cm
(b)
Area of the figure
= (2 x 51 x 13) + (2 x 5 x 13) + (20 x 13)
= (2 x 663) + (2 x 65) + 260
= 1326 + 130 + 260
= 1716 cm
2 Answer(s): (a) 354 cm; (b) 1716 cm
