Question

Find the approximate length of the diagonal of the rectangle.

A) 4.3 cm
B) 6 cm
C) 9.4 cm
D) 12 cm

Answer 1

Option A.
`4.3\ cm`

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`
