The figure not drawn to scale shows Square X and Square Y inside Square TUVW. The area of Square X is 16 m
2 and the area of Square TUVW is 169 m
2.
- Find the length of one side of Square Y.
- Find the perimeter of the shaded region.
(a)
Length of Square X
= √16
= 4 m
Length of Square TUVW
= √169
= 13 m
Length of Square Y
= 13 - 4
= 9 m
(b)
Perimeter of the shaded region
= (2 x 13) + (2 x 9)
= 26 + 18
= 44 m
Answer(s): (a) 13 m; (b) 44 m
