In a retangle the length and breadth are in the ratio 5:3. What is the ratio of its length to its perimeter?

❥${\underline{\underline{\large{\mathtt{EXPLANATION:-}}}}}$

•GIVEN :

• The length and breadth are in the ratio 5:3.

•TO FIND :

• Ratio of length to perimeter of the rectangle.

• SOLUTION :

Let the length of the rectangle be 5x and the breadth of the rectangle be 3x.

We know,

${\boxed{\sf{\green{Perimeter\: of\:rectangle=2(Length+Breadth)}}}}$

So, Perimeter =2(5x+3x)

→ Perimeter= 2 × 8x

→ Perimeter = 16x

Length = 5x

Perimeter = 16x

$\sf{Length\::\: Perimeter}$

$\implies\sf{5x\::\:16x}$

$\implies\sf{5\::\:16}$

❥${\underline{\underline{\large{\mathtt{ANSWER:-}}}}}$

The ratio of its length to its perimeter is 5 : 16.
