Answer:
The length of the diagonal is 65 units
Step-by-step explanation:
To calculate its diagonal we have to use the Pythagorean theorem
the diagonal would be the hypotenuse and the length and width the legs
l1 = 33
l2 = 56
h = hyoptenuse
h² = l1² + l2²
h = √(l1² + l2²)
h = √ (33² + 56²)
h = √ (1089 + 3136)
h = √ 4225
h = 65
The length of the diagonal is 65 units
