Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (56 + (5 x 15) + 16 + 52)
= 2 x (56 + 75 + 16 + 52)
= 2 x 199
= 398 cm
(b)
Area of the figure
= (2 x 56 x 15) + (2 x 4 x 15) + (20 x 15)
= (2 x 840) + (2 x 60) + 300
= 1680 + 120 + 300
= 2100 cm
2 Answer(s): (a) 398 cm; (b) 2100 cm
