Answer 1

61 will be the answer
it follows Pythagoras triplet ,than diagonal become hypo.
11,60,61 will be the Pythagoras triplet

Answer 2

In a rectangle, diagonal is the hypotenuse 
P=11cm
B=60cm
∵H²=P²+B²
∴H²=(11)²+(60)²
H²=121+3600
H²=3721
√H²=√3721
H=61cm
∵H is the diagonal,
∴The diagonal of the rectangle with sides 11cm and 60cm is 61cm
