Answer 2

Answer :-

• Length of the Rectangle = 10 cm

Given :-

• Width of Rectangle = 5 cm
• Perimeter of Rectangle = 30 cm

To Find :-

• Length of the Rectangle = ?

Explanation :-

Let the Length of the Rectangle to be 'x' cm.

$\boxed { \boxed { \bf \longrightarrow Perimeter \: of \: Rectangle = 2 (Length + Width) }}$

Now Substituting the values,

$\rm \longrightarrow 2 (L + B) = 30 \: cm$

$\rm \longrightarrow 2 (x + 5) = 30 \: cm$

$\rm \longrightarrow (x + 5) = \dfrac{30}{2} \: cm$

$\rm \longrightarrow (x + 5) = 15 \: cm$

$\rm \longrightarrow x = 15 - 5\: cm$

$\underline { \boxed { \bf \longrightarrow x = 10 \: cm }}$

Hence, the Length of the rectangle is 10 cm.
