Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 16) + 19 + 46)
= 2 x (54 + 80 + 19 + 46)
= 2 x 199
= 398 cm
(b)
Area of the figure
= (2 x 54 x 16) + (2 x 8 x 16) + (27 x 16)
= (2 x 864) + (2 x 128) + 432
= 1728 + 256 + 432
= 2416 cm
2 Answer(s): (a) 398 cm; (b) 2416 cm
