The figure not drawn to scale shows Square X and Square Y inside Square TUVW. The area of Square X is 9 m
2 and the area of Square TUVW is 144 m
2.
- Find the length of one side of Square Y.
- Find the perimeter of the shaded region.
(a)
Length of Square X
= √9
= 3 m
Length of Square TUVW
= √144
= 12 m
Length of Square Y
= 12 - 3
= 9 m
(b)
Perimeter of the shaded region
= (2 x 12) + (2 x 9)
= 24 + 18
= 42 m
Answer(s): (a) 12 m; (b) 42 m
