Answer:

The diagonal of a rectangle is 13cm.

Step-by-step explanation:

Consider the provided information.

It is given that, the length of a rectangle is 12cm and the breadth of a rectangle is 5cm.

And we need to find out the diagonal of a rectangle.

As we know that, the diagonal of a rectangle is always greater then other two sides. i.e.,

In a rectangle, The square of diagonal side of rectangle is equal to the sum of squares of the other two sides.

We know that,

Diagonal = √[(Length)² + (Breadth)²].

By using the formula and substituting all the given values in the formula, we get.

 =  \sqrt{ {(12)}^{2} +  {(5)}^{2} }

 =  \sqrt{144 +  {(5)}^{2} }

 =  \sqrt{144 + 25}

 =  \sqrt{169}

 = 13

Hence, the diagonal of a rectangle of 13cm.

Given that:-

  • Length of rectangle is 12 cm
  • Breadth of rectangle is 5 cm

To Find:-

  • Find the diagonal of rectangle.

Formula to be Used:-

  • Diagonal² = length² + breadth²

Solution:-

➝ Diagonal = √ 12² + 5²

➝ Diagonal = √ 144 + 25

➝ Diagonal = √ 169

➝ Diagonal = 13

Hence ,

  • Diagonal of rectangle is 13 cm
