Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (58 + (5 x 15) + 16 + 54)
= 2 x (58 + 75 + 16 + 54)
= 2 x 203
= 406 cm
(b)
Area of the figure
= (2 x 58 x 15) + (2 x 4 x 15) + (20 x 15)
= (2 x 870) + (2 x 60) + 300
= 1740 + 120 + 300
= 2160 cm
2 Answer(s): (a) 406 cm; (b) 2160 cm
