Question

What is the perimeter of a rectangle whose length is 7mm and breadth is 2.5mm.


Please explain with the whole solution

Answer 1

Answer:

The perimeter of a rectangle whose length is 7mm and breadth 2.5mm is 19mm.

Step-by-step explanation:

Given: Length = 7 mm

Breadth = 2.5 mm

Find: The perimeter of a rectangle.

Formula:  perimeter of a rectangle = 2 (Length + Breadth)

The perimeter of a rectangle = 2(7 + 2.5)

= 2 (9.5)

= 19 mm

So, the perimeter of a rectangle is 19mm.

Answer 2

To find : perimeter of rectangle .

Given : length of rectangle is $7\ mm$ and breadth is $2.5\ mm$ .

Solution :

• According to question we are given that length of rectangle is $7\ mm$ and breadth is $2.5\ mm$.
• To find perimeter we use following formula -

       Perimeter of rectangle $= 2 ( l + b )$

• Substituting the values we get,

        Perimeter of rectangle $= 2 ( 7 + 2.5 )$

                                               $= 2 (9.5 ) \\= 19\ mm$

Hence, perimeter of rectangle is $19\ mm$ .
