Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (53 + (5 x 11) + 13 + 51)
= 2 x (53 + 55 + 13 + 51)
= 2 x 172
= 344 cm
(b)
Area of the figure
= (2 x 53 x 11) + (2 x 2 x 11) + (15 x 11)
= (2 x 583) + (2 x 22) + 165
= 1166 + 44 + 165
= 1375 cm
2 Answer(s): (a) 344 cm; (b) 1375 cm
