The figure not drawn to scale shows Square F and Square G inside Square BCDE. The area of Square F is 36 m
2 and the area of Square BCDE is 225 m
2.
- Find the length of one side of Square G.
- Find the perimeter of the shaded region.
(a)
Length of Square F
= √36
= 6 m
Length of Square BCDE
= √225
= 15 m
Length of Square G
= 15 - 6
= 9 m
(b)
Perimeter of the shaded region
= (2 x 15) + (2 x 9)
= 30 + 18
= 48 m
Answer(s): (a) 15 m; (b) 48 m
