Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (52 + (5 x 17) + 12 + 45)
= 2 x (52 + 85 + 12 + 45)
= 2 x 194
= 388 cm
(b)
Area of the figure
= (2 x 52 x 17) + (2 x 7 x 17) + (19 x 17)
= (2 x 884) + (2 x 119) + 323
= 1768 + 238 + 323
= 2329 cm
2 Answer(s): (a) 388 cm; (b) 2329 cm
