Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (60 + (5 x 17) + 18 + 56)
= 2 x (60 + 85 + 18 + 56)
= 2 x 219
= 438 cm
(b)
Area of the figure
= (2 x 60 x 17) + (2 x 4 x 17) + (22 x 17)
= (2 x 1020) + (2 x 68) + 374
= 2040 + 136 + 374
= 2550 cm
2 Answer(s): (a) 438 cm; (b) 2550 cm
