Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 12) + 14 + 46)
= 2 x (54 + 60 + 14 + 46)
= 2 x 174
= 348 cm
(b)
Area of the figure
= (2 x 54 x 12) + (2 x 8 x 12) + (22 x 12)
= (2 x 648) + (2 x 96) + 264
= 1296 + 192 + 264
= 1752 cm
2 Answer(s): (a) 348 cm; (b) 1752 cm
