Answer 2

Given :-

• The perimeter of a rectangular street is 100cm.

• The length of rectangular street is 45cm.

To Find :-

• It's breath and area.

Solution :-

First Case :-

${ \boxed{ \rm{ \red {Perimeter\: of \:rectangular \:street = 2(l + b) }}}}$

➡ 100 = 2( 45 + b )

➡ 100 = 90 + 2b

➡ 2b = 100 - 90

➡ 2b = 10

➡ b = 5cm

$\bold{{ \underline{\rm{ \blue{Hence, \: The \: breath \: of \: rectangular \: street \: is \: 5cm.}}}}}$

Second Case :-

${ \boxed{ \rm{ \orange{Area \: of \: rectangular \: street = l × b }}}}$

➡ Area of rectangular street = 45 × 5

➡ Area of rectangular street = 225cm²

${\underline {\rm{ \pink{Hence, \: The \: area \: of \: rectangular \: street \: is \: 225cm {}^{2} .}}}}$
