Question

The perimiter of a swimming pool is 168 m. Its length is 4m more than thrice the breadth. Find the length and breath of the pool

Answer 1

Step-by-step explanation:

here your answer.......................

Answer 2

Let the breadth of pool be x m.

Then its length will be (3x + 4) m

Perimeter of rectangle = 2 ( l + b)

$168 = 2(3x + 4 + x) \\ \\ \frac{168}{2} = 4x + 4 \\ \\ 84 = 4x + 4 \\ \\ 84 - 4 = 4x \\ \\ 80 = 4x \\ \\ x = \frac{80}{4} \\ \\ x = 20 \: m$

Breadth = x = 20 m

Length = 3x + 4

= 3 (20) + 4

= 64 m
