Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (53 + (5 x 18) + 12 + 47)
= 2 x (53 + 90 + 12 + 47)
= 2 x 202
= 404 cm
(b)
Area of the figure
= (2 x 53 x 18) + (2 x 6 x 18) + (18 x 18)
= (2 x 954) + (2 x 108) + 324
= 1908 + 216 + 324
= 2448 cm
2 Answer(s): (a) 404 cm; (b) 2448 cm
