Answer 2

Answer:

122 cm

Step-by-step explanation:

Given : Length of rectangle = 22 cm

Breadth of rectangle = 120 cm

As all angles of rectangle measures 90°, so by applying Pythagoras Theorem, we can find out the length of diagonal.

Length of Diagonal →

= √(22)² + (120)²

= √(484 + 14400)

= √(14884)

= 122 cm
