Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (56 + (5 x 17) + 16 + 54)
= 2 x (56 + 85 + 16 + 54)
= 2 x 211
= 422 cm
(b)
Area of the figure
= (2 x 56 x 17) + (2 x 2 x 17) + (18 x 17)
= (2 x 952) + (2 x 34) + 306
= 1904 + 68 + 306
= 2278 cm
2 Answer(s): (a) 422 cm; (b) 2278 cm
