Question

A rectangle has dimension 12cm by 6cm, find it's perimeter and area​

Answer 1

Answer:

If a rectangle has a dimension 12cm by 6cm, then it's perimeter is 36 cm and the area​ of the circle is 72 sq. cm.

Step-by-step explanation:

Given:

A rectangle has dimensions 12cm by 6cm.

length = 12 cm

breadth = 6 cm

Find: The perimeter and area​ of rectangle.

Formula:

Perimeter of rectangle = 2 (length + breadth)

Area of rectangle = length x breadth

Step  1:

Perimeter of rectangle = 2 (length + breadth)

= 2 (12 + 6)

= 2(18)

36 cm

Step  2:

Area of rectangle = length x breadth

= 12 x 6

= 72 sq. cm

Answer 2

Answer:

Perimeter of rectangle is $36$ cm.

  Area of rectangle is $72$ $cm^{2}$.

Step-by-step explanation:

Given : For a rectangle, length = $12$ cm

                                  Breadth = $6$ cm

To find : The perimeter and area of a rectangle =?

Solution :

• It is given that, For a rectangle, length = $12$ cm

                                  Breadth = $6$ cm

• We have to find the perimeter and area of a rectangle.
• Rectangle has four sides in which pair of opposite sides are equal and parallel to each other.
• Perimeter is the sum of all sides of rectangle.
• The formula for perimeter of rectangle is given by,

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

                                           = $2(12+6)$          

                                           = $2*18$

                                            = $36$ cm

• Area of a rectangle is the space which is occupied by the rectangle.

         Area of rectangle = $l*b$

                                   = $12*6$

                                   = $72$ $cm^{2}$

• ∴ Perimeter of rectangle is $36$ cm.

         Area of rectangle is $72$ $cm^{2}$.
