let the diagonal be a. now, as we know that each angle in a rectangle is right angle. thus we have a right angled triangle. now, we can apply pythagoras theorum. a^2 = 54^2 + 72^2 = 2916 + 5184 =8100 thus, a^2 = 8100 thus, a = 90. Thus the diagonal is 90metres.
Use the Pythagoras therom. let the diagonal be x ⇒54²+72²=x² ⇒8100=x² x=90meters
The length of the diagonal of the rectangle, measuring 54 meters by 72 meters, is 90 meters. This is calculated using the Pythagorean theorem. The diagonal is found by taking the square root of the sum of the squares of the length and width.
