Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 17) + 12 + 47)
= 2 x (51 + 85 + 12 + 47)
= 2 x 195
= 390 cm
(b)
Area of the figure
= (2 x 51 x 17) + (2 x 4 x 17) + (16 x 17)
= (2 x 867) + (2 x 68) + 272
= 1734 + 136 + 272
= 2142 cm
2 Answer(s): (a) 390 cm; (b) 2142 cm
