Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (59 + (5 x 15) + 12 + 50)
= 2 x (59 + 75 + 12 + 50)
= 2 x 196
= 392 cm
(b)
Area of the figure
= (2 x 59 x 15) + (2 x 9 x 15) + (21 x 15)
= (2 x 885) + (2 x 135) + 315
= 1770 + 270 + 315
= 2355 cm
2 Answer(s): (a) 392 cm; (b) 2355 cm
