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
45 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
=
45 x 100
= 80 m
2 Breadth of the turtle pond
= 80 ÷ 10
= 8 m
(b)
Breadth of the grass patch
= 10 + 8
= 18 m
Length of the grass patch
= 18 x 2
= 36 m
Answer(s): (a) 8 m; (b) 36 m
