Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (52 + (5 x 19) + 15 + 46)
= 2 x (52 + 95 + 15 + 46)
= 2 x 208
= 416 cm
(b)
Area of the figure
= (2 x 52 x 19) + (2 x 6 x 19) + (21 x 19)
= (2 x 988) + (2 x 114) + 399
= 1976 + 228 + 399
= 2603 cm
2 Answer(s): (a) 416 cm; (b) 2603 cm
