Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (52 + (5 x 12) + 12 + 44)
= 2 x (52 + 60 + 12 + 44)
= 2 x 168
= 336 cm
(b)
Area of the figure
= (2 x 52 x 12) + (2 x 8 x 12) + (20 x 12)
= (2 x 624) + (2 x 96) + 240
= 1248 + 192 + 240
= 1680 cm
2 Answer(s): (a) 336 cm; (b) 1680 cm
