Question

1. Adjacent sides of a rectangle are 7 cm and 24 cm. Find the length of its
diagonal.
Activity: Let ABCD is a rectangle, in which seg BD is diagonal and AD= 7 cm
AB = 24 cmZA = 90° ...( Each angle of a rectangle is a right angle)
In a right angled A ABD,
BD2 = AD2 +
2
BD2 =
2 + ( 24 )
BD2 = 49 + 576 =
BD =
cm.
The length of the diagonal is
cm.​

Answer 1

Answer:

length of the diagonal is

$\sqrt{ {7}^{2} + {24}^{2} } = \sqrt{49 + 576}$

$= \sqrt{625 } = 25$
