Question

find the length of the diagonal of rectangle whole side are 15 cm and 8 cm​

Answer 1

Answer:length of diagonal is 17 cm

Step-by-step explanation:

Rectangle's sides are 15 cm and 8cm respectively

Then, by the Pythagoras theorem,

Diagonal's length = √(15^2+8^2) = √(225+64) = √289 = 17 cm

Answer 2

Answer:

The length of the diagonal will be 17cm.

Step-by-step explanation:

In context to questions asked

We have to determine the length of the diagonal,

Given that,

Length ( L ) = $15$cm

Breath ( B ) = $8$cm

For calculating the diagonal,

The formula to be used:-

$\text { Diagonal }=\sqrt{(\text { length })^{2}+(\text { breath })^{2}}$

Now, plug the values in the formula:

=> $\text { Diagonal }=\sqrt{(\text { 15 })^{2}+(\text { 8})^{2}}$

                   $=\sqrt{(225+64)}$

                   $=\sqrt{289}$

=> $\text { Diagonal }=17cm$        

So, the required diagonal will be 17cm.
