Question

Find the approximate length of the diagonal of the rectangle.

Answer 1

Answer:

Option A. $4.3\ cm$

Step-by-step explanation:

we know that

To find the diagonal of the rectangle apply the Pythagoras Theorem

Let

D-----> the diagonal of rectangle

L----> the length of rectangle

W---> the width of rectangle

so

$D^{2}=L^{2}+W^{2}$

substitute the values

$D^{2}=3.6^{2}+2.4^{2}$

$D^{2}=18.72$

$D=4.3\ cm$
