Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 17) + 17 + 46)
= 2 x (51 + 85 + 17 + 46)
= 2 x 199
= 398 cm
(b)
Area of the figure
= (2 x 51 x 17) + (2 x 5 x 17) + (22 x 17)
= (2 x 867) + (2 x 85) + 374
= 1734 + 170 + 374
= 2278 cm
2 Answer(s): (a) 398 cm; (b) 2278 cm
