Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 19) + (4 x 2) + (4 x 3)
= 76 + 8 + 12
= 96 cm
(b)
Length of AB
= 19 - 3 - 3
= 13 cm
Length of CD
= 19 - 2 - 2
= 15 cm
Area of the figure
= (19 x 19) - (2 x (13 x 2)) - (2 x (15 x 3))
= 361 - 52 - 90
= 219 cm
2 Answer(s): (a) 96 cm; (b) 219 cm
