Half a rectangle is a right angled triangle. Pythagoras : Triangle whose hypotenuse is 5 and one side is 1 unit greater than the third must be a 3-4-5 triangle, so the rectangle is 3 cm x 4 cm
15 cm for the diagonal.
Using Pythagoras' theorem the length of the diagonal is 20 feet
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = √149 BD = 12.207 So, the length of the diagonal is 12.21 inches.

If you know its dimensions then use Pythagoras' theorem to find the length of its diagonals.
The diagonal is 7.21 feet.
Using Pythagoras' theorem it works out as 194.9820505 or 195 centimeters
The dimensions of this rectangle are that its length is equal to 16 centimeters and its width is equal to 9 centimeters. To find these answers, you need to solve for two unknowns L and W in the equations L- W is equal to 7 and 2 x L plus 2 x W is equal to 50, where L is length and W is width.

To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
The length of the diagonal is about 16.03 feet.
Using Pythagoras, the diagonal is sqrt(122 + 162) = sqrt(144 +256) = sqrt(400) = 20 feet.
