Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 14) + 13 + 47)
= 2 x (54 + 70 + 13 + 47)
= 2 x 184
= 368 cm
(b)
Area of the figure
= (2 x 54 x 14) + (2 x 7 x 14) + (20 x 14)
= (2 x 756) + (2 x 98) + 280
= 1512 + 196 + 280
= 1988 cm
2 Answer(s): (a) 368 cm; (b) 1988 cm
