Answer:
The length of a diagonal of the rectangle = 61cm
Step-by-step explanation:
Consider the right triangle ABC in the rectangle ABCD
AB = 60cm. & BC = 11cm.
According to the pythagoras theorem,
(Hypotenuse)² = (Base)² + (Altitude)²
AC² = AB² + BC²
AC² = 60² + 11²
AC² = 3600 + 121
AC² = 3721
AC = √3721
AC = 61cm.
Hence, the length of a diagonal of the rectangle is 61cm.
