Question

if the measurement of the side of a rectangle is 15cm by 30cm. what is its perimeter?

Answer 1

Answer:

the answer to this question is 90

Answer 2

$\sf{Perimeter \: of \: rectangle} = 2 × (L + B)$

$\sf{Here \: given,}$

$\sf{Length = 15cm}$

$\sf{Breadth = 30cm}$

$\sf{So \: Perimeter \: of \: rectangle = 2 × (L+B)}$

$\sf{⇒2 × (15+30)}$

$\sf{⇒2× 45}$

$\sf{⇒90}$

$\sf{Hence \: \: the \: perimeter \: of \: rectangle \: is \: 90cm.}$
