Answer:
The diagonal of the rectangle is 37 cm.
Step-by-step explanation:
Let □◻ABCD be the given rectangle.
AB = 12 cm, BC 35 cm
In ∆ABC, ∠B = 90° [Angle of a rectangle]
∴ AC = AB + BC [Pythagoras theorem]
= 122 + 352 = 144 + 1225
= 1369
∴ AC = 1369−−−−√1369 [Taking square root of both sides]
= 37 cm
