Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (55 + (5 x 19) + 12 + 52)
= 2 x (55 + 95 + 12 + 52)
= 2 x 214
= 428 cm
(b)
Area of the figure
= (2 x 55 x 19) + (2 x 3 x 19) + (15 x 19)
= (2 x 1045) + (2 x 57) + 285
= 2090 + 114 + 285
= 2489 cm
2 Answer(s): (a) 428 cm; (b) 2489 cm
