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
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
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
Diagonal = 17 cm and height = 8 cm so Length = sqrt[172 - 82] = sqrt(225) = 15 cm Then area = length*height = 15*8 = 120 cm2
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.
Using Pythagoras' theorem it works out as 194.9820505 or 195 centimeters
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
If it's a rectangle and you know its length and height then use Pythagoras' theorem to find the length of its diagonal
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
The diagonal is 7.21 feet.
The length of the diagonal is about 16.03 feet.
Diagonal = 17 cm and height = 8 cm so Length = sqrt[172 - 82] = sqrt(225) = 15 cm Then area = length*height = 15*8 = 120 cm2
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.
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.
Using Pythagoras' theorem it works out as 194.9820505 or 195 centimeters
-- A rectangle has no 'formula'. -- The length of the diagonal is 24feet 10.62inches (rounded)
The diagonal is 26cm
The diagonal length is about 18.44 inches.
