Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (59 + (5 x 12) + 18 + 50)
= 2 x (59 + 60 + 18 + 50)
= 2 x 187
= 374 cm
(b)
Area of the figure
= (2 x 59 x 12) + (2 x 9 x 12) + (27 x 12)
= (2 x 708) + (2 x 108) + 324
= 1416 + 216 + 324
= 1956 cm
2 Answer(s): (a) 374 cm; (b) 1956 cm
