Given the figure that is not drawn to scale, find
- its perimeter.
- its area.
(a)
Perimeter of the figure
= (4 x 13) + (4 x 4) + (4 x 5)
= 52 + 16 + 20
= 88 cm
(b)
Length of AB
= 13 - 5 - 5
= 3 cm
Length of CD
= 13 - 4 - 4
= 5 cm
Area of the figure
= (13 x 13) - (2 x (3 x 4)) - (2 x (5 x 5))
= 169 - 24 - 50
= 95 cm
2 Answer(s): (a) 88 cm; (b) 95 cm
