Answer 2

Answer:-

• length of the rectangle is 4.5 cm.

$\qquad\qquad\underline{\qquad\qquad\qquad\qquad\qquad\qquad}$

Given:

• The perimeter of a rectangle is 13 cm
• its width is 2 cm.

To find:

• Its length

$\qquad\qquad\underline{\qquad\qquad\qquad\qquad\qquad\qquad}$

Understanding concept    

• Here we have to find out the length of the rectangle so firstly we will assume that the length of the rectangle is Y cm. after assuming we will use the simple formula ( Perimeter of a rectangle = 2 [ W + H ] ) where w is width of the rectangle and H is length of the rectangle.

According to the question:-  

Let the length be Y cm.

• Perimeter of a rectangle = 2 [ W + H ]
• 13 cm = 2 [ 2 + Y ]
• 13/2 = 2  + Y
• 6.5 = 2 + Y
• 6.5 - 2 = Y
• 4.5 cm = Y

Hence the length of the rectangle is 4.5 cm.
