The figure not drawn to scale shows Square L and Square M inside Square GHJK. The area of Square L is 16 m
2 and the area of Square GHJK is 100 m
2.
- Find the length of one side of Square M.
- Find the perimeter of the shaded region.
(a)
Length of Square L
= √16
= 4 m
Length of Square GHJK
= √100
= 10 m
Length of Square M
= 10 - 4
= 6 m
(b)
Perimeter of the shaded region
= (2 x 10) + (2 x 6)
= 20 + 12
= 32 m
Answer(s): (a) 10 m; (b) 32 m
