Question

2.The length of diagonal of a Square is 10 cm. The length of
its side is​

Answer 1

Answer: 25√2cm

Step-by-step explanation: suppose ABCD is the square, where AC is the diagonal.

Then triangleABC is a right angled triangle.

By pythagoras' theorem,

AC^2 = AB^2 + BC^2

(10)^2 = a^2 + a^2 [let side of square be =a]

100= 2a^2

100/2 = a^2

50= a^2

√50= a

Therefore, a= 25√2cm
