The figure not drawn to scale shows Square V and Square W inside Square RSTU. The area of Square V is 25 cm
2 and the area of Square RSTU is 121 cm
2.
- Find the length of one side of Square W.
- Find the perimeter of the shaded region.
(a)
Length of Square V
= √25
= 5 cm
Length of Square RSTU
= √121
= 11 cm
Length of Square W
= 11 - 5
= 6 cm
(b)
Perimeter of the shaded region
= (2 x 11) + (2 x 6)
= 22 + 12
= 34 cm
Answer(s): (a) 11 cm; (b) 34 cm
