Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (50 + (5 x 17) + 12 + 42)
= 2 x (50 + 85 + 12 + 42)
= 2 x 189
= 378 cm
(b)
Area of the figure
= (2 x 50 x 17) + (2 x 8 x 17) + (20 x 17)
= (2 x 850) + (2 x 136) + 340
= 1700 + 272 + 340
= 2312 cm
2 Answer(s): (a) 378 cm; (b) 2312 cm
