A boy finds a magical pool. Every time he jumps in the pool, the width shrinks by

3/1



and length shrinks by

2
/1

. He jumps in t
h
e pool a total of 3 times. The final area

of the pool is 4 square meters. The pool was originally 9m wide. What was the

original length of the pool?​

Answer 1

Answer:

The original length of the pool was 8/3 meters.

Step-by-step explanation:

Given, Final area = 4m²

and, Final breadth = 9m

Area = Length × Breadth

4m² = L × 9m

Length = 4m²/9m = 4m/9

By condition,

the pool shrinks by 2 m in length when jumped into it 1 time.

Since, the boy jumped in it 3 times

Therefore, Length shrinked = 2 × 3 = 6 m

Original length = Final length + shrinked length

= 4/9 × 6 = 4/3 × 2 = 8/3 m (ans).
