Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (55 + (5 x 15) + 15 + 51)
= 2 x (55 + 75 + 15 + 51)
= 2 x 196
= 392 cm
(b)
Area of the figure
= (2 x 55 x 15) + (2 x 4 x 15) + (19 x 15)
= (2 x 825) + (2 x 60) + 285
= 1650 + 120 + 285
= 2055 cm
2 Answer(s): (a) 392 cm; (b) 2055 cm
