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 144 m
2. The area of the rectangular turtle pond is
34 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
= √144
= 12 m
Area of the turtle pond
=
34 x 144
= 108 m
2 Breadth of the turtle pond
= 108 ÷ 12
= 9 m
(b)
Breadth of the grass patch
= 12 + 9
= 21 m
Length of the grass patch
= 21 x 2
= 42 m
Answer(s): (a) 9 m; (b) 42 m
