The figure shows a garden in the school with two ponds beside each other. The koi pond is a square pond with an area of 49 m
2. The area of the rectangular turtle pond is
67 of the area of the koi pond. The length of the grass patch is twice the breadth of the grass patch.
- What is the breadth of the turtle pond?
- What is length of the grass patch?
(a)
Length of the koi pond
= √49
= 7 m
Area of the turtle pond
=
67 x 49
= 42 m
2 Breadth of the turtle pond
= 42 ÷ 7
= 6 m
(b)
Breadth of the grass patch
= 7 + 6
= 13 m
Length of the grass patch
= 13 x 2
= 26 m
Answer(s): (a) 6 m; (b) 26 m
