Answer 1

Step-by-step explanation:

$\huge{\underline{\red{\mathrm{♡Answer♡}}}}$

Let the breadth of rectangular swimming pool be x metres.

Then, its length =(2x+2) metres.

We know that the Perimeter of a rectangle =2(Length+Breadth)

=2(2x+2+x)=6x+4

According to the given condition, we have

6x+4=154

⇒6x=154−4 ..[By transposing 4 to RHS]

⇒6x=150

⇒ x = 150

⠀⠀6⠀⠀⠀6 ...[Dividing both sides by 6]

⇒x=25

$\huge{\underline{\red{\mathfrak{♡Answer♡}}}}$

Thus, breadth =25 m and length =25×2+2=52 m

Let the breadth of rectangular swimming pool be x metres.

Then, its length =(2x+2) metres.

We know that the Perimeter of a rectangle:

=2(Length+Breadth)

=2(2x+2+x)=6x+4

According to the given condition, we have

6x+4=154

⇒6x=154−4 ..[By transposing 4 to RHS]

=> 6x = 150

$= > \frac{x}{6} = \frac{150}{6} \: (dividing \: both \: sides \: by \: 6)$

$= > \: x = 25m$

Thus, breadth =25 m and

length =25×2+2=52 m

So the length is 52 m

Hence your answer is 52 m
