Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 14) + 17 + 45)
= 2 x (54 + 70 + 17 + 45)
= 2 x 186
= 372 cm
(b)
Area of the figure
= (2 x 54 x 14) + (2 x 9 x 14) + (26 x 14)
= (2 x 756) + (2 x 126) + 364
= 1512 + 252 + 364
= 2128 cm
2 Answer(s): (a) 372 cm; (b) 2128 cm
