twice its breadth. What are the length and the breadth of the pool?
please step by step ​

Answer 1

Answer:

here it's your solution

Step-by-step explanation:

Solution:

Let the breadth of the pool be x m.

Then, the length of the pool = \left(2x+2\right) m.

Perimeter = 2(l+b)

\Rightarrow\ 154\ =\ 2\left(2x+2+x\right)

\Rightarrow\ \frac{154}{2}=\frac{2\left(2x+2+x\right)}{2}

[Dividing both sides by 2]

\Rightarrow\ 77\ =\ 3x\ +\ 2

\Rightarrow\ 77-2=3x+2-2

[Subtracting 2 from both sides]

\Rightarrow\ 75=3x

\Rightarrow\ \frac{75}{3}=\frac{3x}{3}

[Dividing both sides by 3]

\Rightarrow25=x

\Rightarrow\ x=\ 25\ m

Hence, length of the pool = 2x + 2

2 x 25 + 2 = 50 + 2 = 52 m

And, breadth of the pool = 25 m.
