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 196 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
= √196
= 14 m
Area of the turtle pond
=
12 x 196
= 98 m
2 Breadth of the turtle pond
= 98 ÷ 14
= 7 m
(b)
Breadth of the grass patch
= 14 + 7
= 21 m
Length of the grass patch
= 21 x 2
= 42 m
Answer(s): (a) 7 m; (b) 42 m
