By using Pythagoras' theorem
By using Pythagoras' theorem.
Add all four sides. If you don't know the side lengths then you must know either {height and diagonal from top to bottom-corner} or {diagonal from bottom-center to bottom-corner}. If you know the first two, then use Pythagoras' Theorem to find the second. Now, double that and use Pythagoras' Theorem to find the side length.
Pythagoras' theorem is applicable to right angle triangles
Using Pythagoras theorem its length is 40 cm and so 2(40+30) = 140 cm which is its perimeter
Pythagoras theorem
Use Pythagoras' theorem to find the hypotenuse which works out as 25cm Perimeter = 25+24+7 = 56cm
First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.
Perimeter = 25+36+25+36 = 122 units of measurement Use Pythagoras' theorem to find the other side of the rectangle
34 cm (with the help of Pythagoras' theorem)
28 units (with the help of Pythagoras' theorem)
Pythagoras discovred it to find unknown sides in a right angled triangle

To know about Pythagoras theorem in detail
Although the mathematical facts of the theorem existed - even before humans did - the theorem itself did not exist until Pythagoras thought of it. In that sense, he did not FIND it because it did not exist until he had thought of it.
There are 19 various aspects of Pythagoras theorem.

Use two sides and Pythagoras's theorem to work out the third side. Then simply add the three sides.
