Question

find the breadth of the rectangle whose perimeter is 36 cm and length is 10 cm​

Answer 1

The breadth of the rectangle whose perimeter is 36 cm and length is 10 cm is 2cm.

Given:

The perimeter of a rectangle is 36 cm and the length is 10 cm.

To Find:

The breadth of the rectangle whose perimeter is 36 cm and length is 10 cm.

Solution:

To find the breadth of the rectangle whose perimeter is 36 cm and length is 10 cm we will follow the following steps:

As we know,

Perimeter is the sum of all the sides or boundaries of any geometry or structure.

For example - a square has four sides so the sum of all four sides will be the perimeter.

Also,

The perimeter of a circle is 2πr

But the rectangle has two same sides and two different so their sum will give the perimeter.

So,

The formula of the perimeter of a rectangle =

$2(length + breadth)$

According to the question, the perimeter is 36cm

So,

On putting values we get,

$2(length + breadth) = 36$

$length + breadth = \frac{36}{2} = 12cm$

Length is 10cm

So,

$breadth = (12 - length) = (12 - 10) = 2cm$

Henceforth, the breadth of the rectangle whose perimeter is 36 cm and length is 10 cm is 2cm.
