Answer 2

Answer:

Perimeter of rectangle is $65$ cm.

Step-by-step explanation:

Given : The length of rectangle = $7.5$ cm

          The breadth of rectangle = $25$ cm

To find : Perimeter of rectangle = ?

Solution :

• It is given that, The length of rectangle = $7.5$ cm

                     The breadth of rectangle = $25$ cm

• We have to find the perimeter of rectangle.
• In order to find the perimeter of a rectangle, we should know about what is perimeter.
• Perimeter of the rectangle is the sum of all sides of rectangle i.e. the sum of two lengths and two breadths.
• The perimeter of rectangle is given by the formula,

       Perimeter of rectangle = $2(length+breadth)$

• Putting given values of length and breadth, we get

                                $= 2(7.5+25)$

                                $=2*32.5$

                                $= 65$ cm

• ∴ Perimeter of rectangle is $65$ cm.
