Question

the width of rectangle is 10cm lass than its length and its perimeter is 50cm then the width of rectangle is *​

Answer 1

Answer:

7.5

Step-by-step explanation:

Suppose length of rectangle be X

then,

width of rectangle is x-10cm

According to question

Perimeter of rectangle=50 cm

or, 2(l+b)=50

or, l+b =25

or, x+x-10=25

or,2x=25+10

or,X=35/2

So, X=17.5cm

Length of rectangle=17.5cm

Then,

Width of rectangle=x-10=17.5-10=7.5

Therefore the width of rectangle is 7.5

Answer 2

Given :

⬤ Width of Rectangle is 10 cm less than its Width .

⬤ Perimeter of Rectangle is 50 cm .

To Find :

⬤ Width ot Rectangle .

Formula Used :

$\bf[\:{Perimeter\:of\: Rectangle=2 (l + b)}\:]$

• l = Length
• b = Breadth

Solution :

Let :

• Length of Rectangle be x .
• Breadth of Rectangle be x - 10 .

According to the Formula :-

50 = 2 (l + b)

50 = 2 (x + x - 10)

50 = 2 (2x - 10)

50 = 4x - 20

50 + 20 = 4x

70 = 4x

70/4 = x

17.5 = x

Therefore , The Value of x is 17.5 .

Hence ,

Length of Rectangle = x

= 17.5

Breadth of Rectangle = x - 10

= 17.5 - 10

= 7.5

Therefore , The Length of Rectangle is 17.5 cm and Breadth of Rectangle is 7.5 cm .
