The figure not drawn to scale shows Square E and Square F inside Square ABCD. The area of Square E is 25 m
2 and the area of Square ABCD is 144 m
2.
- Find the length of one side of Square F.
- Find the perimeter of the shaded region.
(a)
Length of Square E
= √25
= 5 m
Length of Square ABCD
= √144
= 12 m
Length of Square F
= 12 - 5
= 7 m
(b)
Perimeter of the shaded region
= (2 x 12) + (2 x 7)
= 24 + 14
= 38 m
Answer(s): (a) 12 m; (b) 38 m
