Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (53 + (5 x 17) + 13 + 46)
= 2 x (53 + 85 + 13 + 46)
= 2 x 197
= 394 cm
(b)
Area of the figure
= (2 x 53 x 17) + (2 x 7 x 17) + (20 x 17)
= (2 x 901) + (2 x 119) + 340
= 1802 + 238 + 340
= 2380 cm
2 Answer(s): (a) 394 cm; (b) 2380 cm
