Question

The perimeter of a rectangle is13 cm and it's width is11/4 cm.Find it's length​

Answer 1

Answer:

Step-by-step explanation:

Given :-

Perimeter of a rectangle = 13 cm

Width of a rectangle = 11/4 cm.

To Find :-

The Length

Formula to be used :-

$\boxed {\underline { Perimeter=2\times(Length+Breadth)}}$

Solution :-

Let the length of rectangle be L.

According to the Question,

$\implies Perimeter=2\times(Length+Breadth$

$\implies 13=2\times(Length+Breadth)$

$\implies Length+\frac{11}{4}= \frac{13}{2}$

$\implies Length=\frac{13}{2}-\frac{11}{4}$

$\implies Length=\frac{26-11}{4}$

$\implies Length=\frac{15}{4}$

Hence. The Length of rectangle is $\frac{15}{4}$ cm.

Answer 2

$\large \bold{ \underline{ \underline{ \: Answer : \: \: \: }}}$

$\to$ Length = 3.75 cm

$\large \bold{ \underline{ \underline{ \: Explaination : \: \: \: }}}$

Given ,

$\star$ Perimeter of rectangle = 13 cm

$\star$ Breadth = 11/4 cm = 2.75 cm

$\large\bold{ \fbox{ \fbox{ \sf Perimeter = 2 ( Length + Breadth ) }}}$

$\to \sf 13 = 2 ( Length + 2.75 ) \\ \\ \to \sf</p><p>6.5 = Length + 2.75 \\ \\ \to \sf</p><p>Length = 6.5 - 2.75 \\ \\ \to \sf </p><p>Length = 3.75 \: cm$

Hence , the length of given rectangle is 3.75 cm
