Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (55 + (5 x 17) + 13 + 46)
= 2 x (55 + 85 + 13 + 46)
= 2 x 199
= 398 cm
(b)
Area of the figure
= (2 x 55 x 17) + (2 x 9 x 17) + (22 x 17)
= (2 x 935) + (2 x 153) + 374
= 1870 + 306 + 374
= 2550 cm
2 Answer(s): (a) 398 cm; (b) 2550 cm
