The figure not drawn to scale shows Square J and Square K inside Square EFGH. The area of Square J is 25 m
2 and the area of Square EFGH is 169 m
2.
- Find the length of one side of Square K.
- Find the perimeter of the shaded region.
(a)
Length of Square J
= √25
= 5 m
Length of Square EFGH
= √169
= 13 m
Length of Square K
= 13 - 5
= 8 m
(b)
Perimeter of the shaded region
= (2 x 13) + (2 x 8)
= 26 + 16
= 42 m
Answer(s): (a) 13 m; (b) 42 m
