cow do you calculate the correct diagonal size in a rectangle or square?

Answer 1

square root of a X a + bX b=c

Answer 2

The Pythagorean Thm. is correct to use.
Let a= width of rectangle.
Let b = length of rectangle.
[If the shape is a square, then the sides are the same; so, a = b.]

The Thm. has been given before:
a^2 + b^2 = c^2 [c represents the diagonal or hypotenuse]
Solve for "c", as others have shown:
c = square root[a^2 + b^2]

Ex. A rectangle with length 3cm & width 4cm. The diagonal will be:
c = sq.rt(9 + 16)
= sq rt(25)
= 5cm

Answer 3

use the Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the lengths of two legs, and c is the length of the diagonal. Hence, for your problem: 5^2 + 3^2 = c^2 25 + 9 = c^2 34 = c^2 c = square root of 34 c = 5.83 - the length of the diagonal of your rectangle

Answer 4

you can calculate the diagonal of a rectangle or square by Pythagorean therorem: a^2 + b^2 = c^2. You are solving for C. C will give you the length of the diagonal, if you know the lengths of the two sides. a and b are the two sides that you plug into the equation.

Answer 5

For a square, the diagonal is = s*sqrt(2), where s is length 1s a side of the square.

For a rectangle with length= l and width = w the diagonal
d = sqrt(l^2 + w^2)

Answer 6

I assume you mean "how"...not "cow"

Pythagorean theorem....Add the square of the length and the height of the rectangle together. Then take the square root of the answer. That's it. In the case of a square (where all sides are equal, it is the square root of twice the square of any side. Simple.

Answer 7

Pythagoras Theorem.
The square root of the sum of the squares of any two adjoining sides in a square or rectangle.

Answer 8

Use the Pythagorean Theorem.

Rectangle of sides a & b
d=√(a^2+b^2)

Square of side s
d=s√2

Answer 9

If cows could do math then...

it would be the square root of [(the length squared) + (the width squared)]

Answer 10

Try Pythagoras
