Encik Rozaimi dan anaknya ingin membina tapak bagi sebuah kolam ikan di tengah-tengah laman belakang rumah
mereka. Kedua-dua tapak kolam dan kawasan laman belakang berbentuk segi empat sama. Diberi panjang laman

belakang tersebut ialah 450 cm dan luas tapak kolam ialah 4.41 m . Bagaimanakah mereka dapat menentukan
kedudukan kolam? KBAT Mengaplikasi
Encik Rozaimi and his son want to build a base of a fish pond in the middle of their backyard. Both the base of the pond and the backyard are in
square shape. Given the length of the backyard is 450 cm and the area of the base of the pond is 4.41 m . How are they going to make sure the
2
position of the fish pond is in the middle of the backyard?

Panjang laman belakang
The length of the backyard
= 450 cm ÷ 100
= 4.5 m Cari jarak di antara kolam dengan setiap sisi
laman belakang.
Find the distance between the pond and each side of the
Panjang tapak kolam backyard.
The length of the pond
= 
4.41

2.1 × 2.1
= 

= 2.1 m
Beza panjang antara laman belakang dengan tapak kolam
The difference in length between the backyard and the base of the pond
= 4.5 m – 2.1 m
= 2.4 m

Jarak di antara kolam dengan setiap sisi laman belakang
Distance between the pond and each side of the backyard Semak Semula
= 2.4 m ÷ 2 Panjang laman belakang
= 1.2 m The length of the backyard
= 2.1 + 2(1.2)
= 2.1 + 2.4
= 4.5 m
= 450 cm

Bagi memastikan kedudukan kolam ikan berada di tengah-tengah laman belakang, jarak antara kolam dengan
setiap sisi laman belakang mestilah 1.2 m.
To make sure the fish pond is in the middle of the backyard, the distance between the pond and each side of the backyard must be 1.2 m.
