Answer 2

Answer :-

2️⃣ 13

Solution:

Adjacent sides of a rectangle and diagonal forms a right angle triangle

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.

5²  + 12²  = Diagonal²

=> 25 + 144 = Diagonal²

=> 169 = Diagonal²

=> 13²  = Diagonal²

=> 13 = Diagonal

Hence diagonal is13cm.*

Adjacent sides of a rectangle are 12 cm and 5 cm then the length of its diagonal is 13cm
