The length of diagonal DG is 21.54 cm and the length of diagonal AG is 24.65 cm.
What is the Pythagoras theorem?
The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
The length of diagonal DG = √(8² + 20²)
= 21.54 cm
The length of diagonal AG:
First, calculate the length of EG = √(12² + 20²) = 23.32 cm
The length of diagonal AG = √(8² + 23.32²)
= 24.65 cm
Thus, the length of diagonal DG is 21.54 cm and the length of diagonal AG is 24.65 cm.
