I believe this makes the 3-4-5 triangle, making the hypotenuse 15 cm
but just in case this is wrong, c^2 = sqrt(a^2 +b^2)
c^2 = sqrt(81+144)= sqrt(225)= 15
Answer: 15 cm

How do you count the number of squares crossed by the diagonal in a rectangle?
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
What is the length of a rectangle if the diagonal and height are given?
If d is the diagonal and h is the height Let, l=length of rectangle we have By pythagrous theorem d square= l square + h square therefore l square= d square - h square
What is the area of a rectangle with a diagonal length of 17 centimeters and height of length 8 centimeters?
Diagonal = 17 cm and height = 8 cm so Length = sqrt[172 - 82] = sqrt(225) = 15 cm Then area = length*height = 15*8 = 120 cm2

How do you work out the diameter of a rectangle?
The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.
