Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (57 + (5 x 11) + 14 + 53)
= 2 x (57 + 55 + 14 + 53)
= 2 x 179
= 358 cm
(b)
Area of the figure
= (2 x 57 x 11) + (2 x 4 x 11) + (18 x 11)
= (2 x 627) + (2 x 44) + 198
= 1254 + 88 + 198
= 1540 cm
2 Answer(s): (a) 358 cm; (b) 1540 cm
