Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (57 + (5 x 15) + 14 + 49)
= 2 x (57 + 75 + 14 + 49)
= 2 x 195
= 390 cm
(b)
Area of the figure
= (2 x 57 x 15) + (2 x 8 x 15) + (22 x 15)
= (2 x 855) + (2 x 120) + 330
= 1710 + 240 + 330
= 2280 cm
2 Answer(s): (a) 390 cm; (b) 2280 cm
