Question

If the length and breadth of a rectangle are 10x and 5x respectively, then find the perimeter of the rectangle.​

Answer 1

Answer:

Length of 10 cm x Width of 5 cm = Cross Sectional Area is 50 square cm

Length of 10 cm each x 2 = 20 cm

Width of 5 cm x each 2 = 10 cm

Perimeter Total is 20 cm +10 cm = 30 cm.

Answer 2

Answer:

The perimeter of rectangle is $30x$ units.

Step-by-step explanation:

Given : In a rectangle, length = $10x$

                                breadth = $5x$

To find : The perimeter of the rectangle = ?

Solution :

• It is given that, in a rectangle, length = $10x$

                                breadth = $5x$

• We have to find the perimeter of the rectangle.
• We know that perimeter of the rectangle is the sum of all sides of the rectangle.
• The formula for perimeter of rectangle is given by,

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

• Put the values of length and breadth, we get

                                          = $2(10x+5x)$  

                                          = $2*15x$

                                          = $30x$ units.

• ∴ The perimeter of rectangle is $30x$ units.
