The figure not drawn to scale shows Square S and Square T inside Square NPQR. The area of Square S is 9 m
2 and the area of Square NPQR is 100 m
2.
- Find the length of one side of Square T.
- Find the perimeter of the shaded region.
(a)
Length of Square S
= √9
= 3 m
Length of Square NPQR
= √100
= 10 m
Length of Square T
= 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
