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