How do you find the width and length of a rectangle if you only know the diagnol?

If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.


How can you find the length of the diagonal base of a rectangle box that has an 24 centimeters long 18 centimeters wide and 10 centimeters high?

The base is 24 cm x 18 cm. By Pythagoras, the diagonal of the base is sqrt(242 + 182) = sqrt(576 + 324) = sqrt(900) = 30 cm

A rectangle is 3 meters wide and 10 meters long how long is the diagonal of the rectangle?

To find the length of the diagonal in a rectangle, use the formula for calculating the hypotenuse of a right triangle: a² = b² + c². a² = 3² + 10² a² = 9 + 100 a² = 109 a = 10.44 m


What is the length of a diagonal of a rectangle 24 inches long and 10 inches wide?

Using Pythagoras' theorem it is 26 inches in length


How long is the diagonal of a rectangle with dimensions 7in by 10in?

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.

What is the width of the rectangle if A rectangle is 25 centimeters long and The perimeter is 84 centimeters.?

To find the width of the rectangle, we need to subtract twice the length from the perimeter. Given that the length is 25 centimeters and the perimeter is 84 centimeters, twice the length would be 50 centimeters. Subtracting 50 from 84 gives us a width of 34 centimeters for the rectangle.
