Question

Draw a square PQRS in which a diagonal measures 9.8 cm. Write down the measurement of a side of the square.

Answer 1

Answer:

6.9296 cm

Step-by-step explanation:

Diagonal = 9.8 cm

Let the length of side of square be 'a'

Using Pythagoras theorem,

a^2 + a^2 = 9.8^2

2(a^2) = (9.8^2)

a = 6.9296 cm
