​

Answer 1

QUESTION:

The perimeter of a rectangle is 13 cm and its width is 2 whole 3/4 cm. Find its length.

$———————————————$

GIVEN:

$Perimeter=13cm$

$Width=2 \frac{3}{4} \: cm = \frac{11}{4} \: cm$

$———————————————$

TO FIND:

Length of rectangle.

$———————————————$

As you know,

for calculating perimeter of a rectangle,the formula mainly used is,

$p = 2(l + b)$

where 'p' stands for perimeter,

'l' stands for length and

'b' stands for breadth/width.

$———————————————$

Now, in our question breadth/width and perimeter are mentioned.

So, insert the values of breadth/width and perimeter in the formula and let the length be 'l'.

After inserting,we will get,

$13 = 2(l + \frac{11}{4} )$

$———————————————$

Now, let's solve the equation and get the value of 'l'.

$13 = 2(l + \frac{11}{4} )$

$= = > 13 = 2l + \frac{11}{2}$

$= = > 13 - \frac{11}{2} = 2l$

$= = > \frac{26 - 11}{2} = 2l$

$= = > \frac{15}{4} = l$

$———————————————$

$Hence \: the \: value \: of \: 'l' \: or \: length \: is \\ \: \frac{15}{4}cm \: or \: 3 \frac{3}{4} cm$
