Answer 1

Given the perimeter of a rectangular swimming pool is 164m and It's length is 2m more than twice its breadth.

We have to find, Length and breadth of the pool.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Let ,Breadth of the pool be x

and, Length will be (2x + 2)

According to the question,

we know that,

$\star\;{\boxed{\sf{\pink{Perimeter_{\;(rectangle)} = 2 (l + b) }}}}$

Where,

l = length

b = breadth.

$:\implies\sf 2 [(2x + 2) + x] = 164$

$:\implies\sf 2 [ 2x + 2 + x ] = 164$

$:\implies\sf 2 [ 3x + 2 ] = 164$

$:\implies\sf 3x + 2 = \cancel{\dfrac{164}{2}}$

$:\implies\sf 3x + 2 = 82$

$:\implies\sf 3x = 82 - 2$

$:\implies\sf 3x = 80$

$:\implies\sf x = \cancel{\dfrac{80}{3}}$

$:\implies{\boxed{\frak{\purple{ x = 26.66 }}}}\\\bigstar$

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

Now,

Breadth of the rectangle = 26.66m

Length of the rectangle = 26.66(2) + 2 = 55.32m

$\therefore\;{\underline{\sf{ Hence, \;the\: length\; and \;breadth \;are \;55.32m \;and \;26.66m\; respectively.}}}$

Answer 2

Answer:

no it's length will be 82 m
