Answer:

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} }=

(12)

2

+(5)

2

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

144+(5)

2

= \sqrt{144 + 25}=

144+25

= \sqrt{169}=

169

= 13=13

Hence, the diagonal of a rectangle of 13cm.
