Question

How Will You Find Diagonal Of Rectangle

Answer 1

Answer:

To find the diagonal of a rectangle formula, you can divide a rectangle into two congruent right triangles, i.e., triangles with one angle of 90°. Each triangle will have sides of length l and w and a hypotenuse of length d .

MARK ME BRAINLIEST!!!

Answer 2

Suppose a Rectangle ABCD and a diagonal AC

Now,

In △ABC, by Pythagoras Theorem

[ because every interior angle of a rectangle is 90° ]

So,

AC² = AB² + BC²

AC = √AB² + BC²

Here, AC is the diagonal.

Similarly we can find the other diagonal ( i.e, BD )

BD = √AD² + AB²
