The figure not drawn to scale shows Square W and Square X inside Square STUV. The area of Square W is 16 m
2 and the area of Square STUV is 100 m
2.
- Find the length of one side of Square X.
- Find the perimeter of the shaded region.
(a)
Length of Square W
= √16
= 4 m
Length of Square STUV
= √100
= 10 m
Length of Square X
= 10 - 4
= 6 m
(b)
Perimeter of the shaded region
= (2 x 10) + (2 x 6)
= 20 + 12
= 32 m
Answer(s): (a) 10 m; (b) 32 m
