Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (55 + (5 x 12) + 13 + 53)
= 2 x (55 + 60 + 13 + 53)
= 2 x 181
= 362 cm
(b)
Area of the figure
= (2 x 55 x 12) + (2 x 2 x 12) + (15 x 12)
= (2 x 660) + (2 x 24) + 180
= 1320 + 48 + 180
= 1548 cm
2 Answer(s): (a) 362 cm; (b) 1548 cm
