​

Answer 1

diagonal of a rectangle is hypotenuse of length and breadth of a rectangle because every interior angle of rectangle is 90 degree

Given

Length = 30cm

Breadth = 40cm

according to question

30^2 + 40^2 = diagonal^2

900 + 1600 diagonal^2

2500 = diagonal ^2

diagonal = 50cm

Answer 2

Step-by-step explanation:

d=√w²+l²= √402+302= 50cm
