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 64 m
2. The area of the rectangular turtle pond is
78 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
= √64
= 8 m
Area of the turtle pond
=
78 x 64
= 56 m
2 Breadth of the turtle pond
= 56 ÷ 8
= 7 m
(b)
Breadth of the grass patch
= 8 + 7
= 15 m
Length of the grass patch
= 15 x 2
= 30 m
Answer(s): (a) 7 m; (b) 30 m
