Question

the length of rectangle is 15 cm and width is 10 cm find the perimeter of rectangle ​

Answer 1

$perimeter = 2(l + b) \\ 2(15 + 10) \\ 2(25) \\ 50cm$

Answer 2

$\huge \boxed { \blue{\bold{Answer}}}$

It is given that ,

star⋆ Breadth = 15 cm

star⋆ Breadth = 15 cmstar⋆ Length = 3 (breadth)

= 3(15)

= 45 cm

We know that , the perimeter of rectangle is given by

Perimeter = 2(Length+ breadth )

Perimeter = 2(Length+ breadth )

2(45+15)

=2(60)

=120cm

Thus , the perimeter of rectangle is 120 cm
