Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (53 + (5 x 15) + 19 + 47)
= 2 x (53 + 75 + 19 + 47)
= 2 x 194
= 388 cm
(b)
Area of the figure
= (2 x 53 x 15) + (2 x 6 x 15) + (25 x 15)
= (2 x 795) + (2 x 90) + 375
= 1590 + 180 + 375
= 2145 cm
2 Answer(s): (a) 388 cm; (b) 2145 cm
