Answer 2

It is given that ,

$\star$Breadth = 15 cm

$\star$Length = 3 (breadth)

= 3(15)

= 45 cm

We know that , the perimeter of rectangle is given by

$\large \fbox{ \fbox{ \sf \: Perimeter = 2(Length+ breadth ) }}$

$</p><p> \sf = 2(45+ 15) \\ \\ </p><p> \sf = 2(60) \\ \\ </p><p> \sf = 120 \: \: cm$

Thus , the perimeter of rectangle is 120 cm
