Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (52 + (5 x 16) + 13 + 43)
= 2 x (52 + 80 + 13 + 43)
= 2 x 188
= 376 cm
(b)
Area of the figure
= (2 x 52 x 16) + (2 x 9 x 16) + (22 x 16)
= (2 x 832) + (2 x 144) + 352
= 1664 + 288 + 352
= 2304 cm
2 Answer(s): (a) 376 cm; (b) 2304 cm
