Answer:
The length of diagonal AC is 61 cm
Given ABCD is a rectangle AB = 11cm, BC=60cm. we have to find the length of AC i.e length of diagonal.
AB=11 cm
BC=60 cm
As all angles of rectangle are right angles implies ZA=ZB=ZC=ZD=90°
In AABC, by Pythagoras theorem
Hypotenuse² Base²+ Perpen
Diagonal2=AB²+ BC²
AC² = 112 + 60² AC² = 3720
AC = √3721 = 61cm
Hence, length of AC is 61 cm
