Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (56 + (5 x 12) + 13 + 51)
= 2 x (56 + 60 + 13 + 51)
= 2 x 180
= 360 cm
(b)
Area of the figure
= (2 x 56 x 12) + (2 x 5 x 12) + (18 x 12)
= (2 x 672) + (2 x 60) + 216
= 1344 + 120 + 216
= 1680 cm
2 Answer(s): (a) 360 cm; (b) 1680 cm
