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 100 m
2. The area of the rectangular turtle pond is
12 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
= √100
= 10 m
Area of the turtle pond
=
12 x 100
= 50 m
2 Breadth of the turtle pond
= 50 ÷ 10
= 5 m
(b)
Breadth of the grass patch
= 10 + 5
= 15 m
Length of the grass patch
= 15 x 2
= 30 m
Answer(s): (a) 5 m; (b) 30 m
