योग

उत्तर

Suppose ABCD is a rectangle.

Here, segment AC is a diagonal and segment AD is one side of the rectangle ABCD.

l(AC) = 26 cm and l(AD) = 24 cm.

In right ∆ACD,

l(AC)2 = l(AD)+ l(CD)2  ...(Pythagoras theorem)

⇒ l(CD)= l(AC)2 − l(AD)2

⇒ l(CD)= (26)2 − (24)2

⇒ l(CD)2 = 676 − 576 = 100

⇒ l(CD) =  `sqrt(100)` = 10 cm

Thus, the other side of the rectangle is 10 cm.
