Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (54 + (5 x 18) + 15 + 50)
= 2 x (54 + 90 + 15 + 50)
= 2 x 209
= 418 cm
(b)
Area of the figure
= (2 x 54 x 18) + (2 x 4 x 18) + (19 x 18)
= (2 x 972) + (2 x 72) + 342
= 1944 + 144 + 342
= 2430 cm
2 Answer(s): (a) 418 cm; (b) 2430 cm
