Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 12) + 16 + 47)
= 2 x (51 + 60 + 16 + 47)
= 2 x 174
= 348 cm
(b)
Area of the figure
= (2 x 51 x 12) + (2 x 4 x 12) + (20 x 12)
= (2 x 612) + (2 x 48) + 240
= 1224 + 96 + 240
= 1560 cm
2 Answer(s): (a) 348 cm; (b) 1560 cm
