Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (59 + (5 x 12) + 15 + 57)
= 2 x (59 + 60 + 15 + 57)
= 2 x 191
= 382 cm
(b)
Area of the figure
= (2 x 59 x 12) + (2 x 2 x 12) + (17 x 12)
= (2 x 708) + (2 x 24) + 204
= 1416 + 48 + 204
= 1668 cm
2 Answer(s): (a) 382 cm; (b) 1668 cm
