Answer 2

${\large{\bf{\red{\clubs{\underline{Given :}}}}}}$

The length of the room is 2.5 times its breath.if the perimeter of the room is 70m.

${\large{\bf{\blue{\clubs{\underline{To Find:}}}}}}$

Find its length.

￣￣￣￣￣￣￣￣￣￣￣￣

${\large{\bf{\orange{\clubs{\underline{Formula \: used :}}}}}}$

${\sf{\pink{Perimeter = 2( L+B )}}}$

Where,

${\sf{\purple{L = Length}}}$

${\sf{\purple{B = Breadth}}}$

${\large{\bf{\green{\clubs{\underline{Solution :}}}}}}$

Let B be x :

${\sf{\purple{Breadth = x}}}$

${\sf{\purple{Length = x + 2.5}}}$

Than,

${\sf{\pink{Perimeter = 2( L+B )}}}$

${\sf{\purple{70m = 2( x+x + 2.5 )}}}$

${\sf{\purple{70m = 2( 2x + 2.5 )}}}$

${\sf{\purple{70m = 4x + 5}}}$

${\sf{\purple{70 - 5 = 4x }}}$

${\sf{\purple{{\cancel \frac{65}{4} = x }}}}$

${\bf{\red{\boxed{X = 16. 25m}}}}$

Hence,

${\bf{\red{Breadth = 16.25}}}$

= 16.25 + 2.5

= 18.75m

So,

The length is 18.75m.
