Question

Length is 12m and width is 8m. Find the perimeter

Answer 1

Given length of rectangle = 12m

Given Breadth or Width of rectangle = 8m.

Formula for perimeter of rectangle = 2×(l+b)

=2×(12+8) m

= 2x20 m

= 40m.

Therefore the area of rectangle = 40m.

Answer 2

Given,

The length is 12m and the width is 8m.

To Find,

The perimeter =?

Solution,

We can solve the question as follows:

It is given that the length and width of a rectangle are 12 m and 8 m respectively. We have to find the perimeter.

$Length = 12\: m$

$Width = 8\: m$

The formula for the perimeter of a rectangle is as:

$Perimeter = 2(Length + Width)$

To find the perimeter, we will substitute the given values in the above formula.

$Perimeter = 2(12 + 8)$

                 $= 2*20$

                 $= 40\: m$

Hence, the perimeter of the rectangle is 40 m.
