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