Q2 of 35 Page 73

Adjacent sides of a rectangle are 7 cm and 24 cm. Find the length of its diagonal.

Adjacents sides are 7cm and 24 cm

In a rectangle angle between the adjacent sides is 90°


⇒ the diagonal is hypotenuse of right Δ


By pythagorus theorem


Hypotenuse2 = side2 + side2


Hypotenuse2 = 49 + 576 =


length of the diagonal = 25cm
