Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (50 + (5 x 15) + 12 + 48)
= 2 x (50 + 75 + 12 + 48)
= 2 x 185
= 370 cm
(b)
Area of the figure
= (2 x 50 x 15) + (2 x 2 x 15) + (14 x 15)
= (2 x 750) + (2 x 30) + 210
= 1500 + 60 + 210
= 1770 cm
2 Answer(s): (a) 370 cm; (b) 1770 cm
