The figure not drawn to scale shows Square G and Square H inside Square CDEF. The area of Square G is 9 cm
2 and the area of Square CDEF is 121 cm
2.
- Find the length of one side of Square H.
- Find the perimeter of the shaded region.
(a)
Length of Square G
= √9
= 3 cm
Length of Square CDEF
= √121
= 11 cm
Length of Square H
= 11 - 3
= 8 cm
(b)
Perimeter of the shaded region
= (2 x 11) + (2 x 8)
= 22 + 16
= 38 cm
Answer(s): (a) 11 cm; (b) 38 cm
