The figure not drawn to scale shows Square Q and Square R inside Square LMNP. The area of Square Q is 9 m
2 and the area of Square LMNP is 100 m
2.
- Find the length of one side of Square R.
- Find the perimeter of the shaded region.
(a)
Length of Square Q
= √9
= 3 m
Length of Square LMNP
= √100
= 10 m
Length of Square R
= 10 - 3
= 7 m
(b)
Perimeter of the shaded region
= (2 x 10) + (2 x 7)
= 20 + 14
= 34 m
Answer(s): (a) 10 m; (b) 34 m
