Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (60 + (5 x 15) + 16 + 53)
= 2 x (60 + 75 + 16 + 53)
= 2 x 204
= 408 cm
(b)
Area of the figure
= (2 x 60 x 15) + (2 x 7 x 15) + (23 x 15)
= (2 x 900) + (2 x 105) + 345
= 1800 + 210 + 345
= 2355 cm
2 Answer(s): (a) 408 cm; (b) 2355 cm
