If the length and width of a rectangle are 15.1 by 13.0, then you can use the pythagorean theorem to calculate the length of the diagonal since it forms a right triangle. The pythagorean formula is a^2 + b^2 = c^2." Let a=15.1 and b=13.
Beside this, how do you find the length of the diagonal of a square?
To find the length of the diagonal of a square, multiply the length of one side by the square root of 2: If the length of one side is x The diagonals of a square intersect (cross) in a 90 degree angle. This means that the diagonals of a square are perpendicular.
Additionally, what is the diagonal of a triangle? To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse.
Also question is, how do you find the length of a rectangle?
Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

What is the length of the diagonal of a square with sides of length 7?
The length of the diagonal of a square with sides 7 cm long is equal to the length of the hypotenuse of an isosceles right triangle (45–45–90 triangle) with legs 7 cm long. In a 45–45–90 right triangle, the length of the hypotenuse is sqrt(2) times the length of a leg, so the diagonal of the square is 7sqrt(2) cm long.Is the diagonal of a square equal to its side?
