The length of the diagonal, EG, in this rectangle using Pythagoras theorem is 8.7 cm
What is the length of the diagonal of the rectangle is the hypotenuse?
The length of the diagonal of the rectangle is the hypotenuse.
Hypotenuse² = Opposite² - Adjacent²
= 6² + 6.3²
= 36 + 39.69
Hypotenuse² = 75.69
Find the square root of both sides
Hypotenuse = √75.69
Hypotenuse = 8.7 cm
Therefore, diagonal EG equals 8.7 cm
