The figure not drawn to scale shows Square N and Square P inside Square JKLM. The area of Square N is 16 m
2 and the area of Square JKLM is 169 m
2.
- Find the length of one side of Square P.
- Find the perimeter of the shaded region.
(a)
Length of Square N
= √16
= 4 m
Length of Square JKLM
= √169
= 13 m
Length of Square P
= 13 - 4
= 9 m
(b)
Perimeter of the shaded region
= (2 x 13) + (2 x 9)
= 26 + 18
= 44 m
Answer(s): (a) 13 m; (b) 44 m
