The figure not drawn to scale shows Square H and Square J inside Square DEFG. The area of Square H is 9 m
2 and the area of Square DEFG is 64 m
2.
- Find the length of one side of Square J.
- Find the perimeter of the shaded region.
(a)
Length of Square H
= √9
= 3 m
Length of Square DEFG
= √64
= 8 m
Length of Square J
= 8 - 3
= 5 m
(b)
Perimeter of the shaded region
= (2 x 8) + (2 x 5)
= 16 + 10
= 26 m
Answer(s): (a) 8 m; (b) 26 m
