Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (56 + (5 x 15) + 19 + 51)
= 2 x (56 + 75 + 19 + 51)
= 2 x 201
= 402 cm
(b)
Area of the figure
= (2 x 56 x 15) + (2 x 5 x 15) + (24 x 15)
= (2 x 840) + (2 x 75) + 360
= 1680 + 150 + 360
= 2190 cm
2 Answer(s): (a) 402 cm; (b) 2190 cm
