$\huge\underline\pink{QUESTION}$
​
The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?​

Answer 1

Answer:

So, Length=AB=CD=(2x+2) and Breadth=BC=AD=x. The breadth of the rectangular swimming pool = 25 m. m. Therefore, the length and breadth of the rectangular swimming pool is 52 m and 25 m respectively.

Answer 2

$\tt\large{\hookrightarrow Given}$

$\large{\sf{Perimeter~=~154m}}$

$\mathtt \color{blue}{To~be~assumed}$

$\large{\sf{Let~breadth~be~x}}$

$\large{\sf{So~Length~=~2x~+~2}}$

$\tt\large{\hookrightarrow To~find~}$

Length & Breadth

$\tt{\large\hookrightarrow Solution}$

$\fbox\blue{Perimeter~→~2~(l~+~b)}$

${\sf\bold{According~to~qu.}}$

$\large{\sf{2~(x~+~2x~+~2)~=~154}}$

$\large{\sf{2(3x~+~2)~=~154}}$

$\large{\sf{6x~+~4~=~154}}$

$\large{\sf{6x~=~154~-~4}}$

$\large{\sf{6x~=~150}}$

$\large{\sf{x=~\frac{150}{6} }}$

${\sf\bold{x~=~25}}$

$\large{\sf{\color{maroon}{Length~=~52m}}}$

$\large{\sf{\color{maroon}{Breadth~=~25m}}}$
