The figure not drawn to scale shows Square L and Square M inside Square GHJK. The area of Square L is 25 m
2 and the area of Square GHJK is 196 m
2.
- Find the length of one side of Square M.
- Find the perimeter of the shaded region.
(a)
Length of Square L
= √25
= 5 m
Length of Square GHJK
= √196
= 14 m
Length of Square M
= 14 - 5
= 9 m
(b)
Perimeter of the shaded region
= (2 x 14) + (2 x 9)
= 28 + 18
= 46 m
Answer(s): (a) 14 m; (b) 46 m
