The figure not drawn to scale shows Square S and Square T inside Square NPQR. The area of Square S is 25 m
2 and the area of Square NPQR is 169 m
2.
- Find the length of one side of Square T.
- Find the perimeter of the shaded region.
(a)
Length of Square S
= √25
= 5 m
Length of Square NPQR
= √169
= 13 m
Length of Square T
= 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
