Answer 2

$\huge{\underline{\underline\green{</p><p>Ânswer}}}$

given,

$area \: of \: rectangle = {1050cm}^{2} \\ length = 35cm$

we know that

area of rectangle = length×breadth

1050 =35×breadth

1050÷35=breadth

breadth=30cm

${\underline{\underline\red{\mathrm{we \: need \: to \: find \: that}}}}$

perimeter of rectangle =2(l+b)

=2(30+35)

=2(65)

perimeter=130cm
