Question

If the diagonal of a square is 12cm long.
Find its area and length of one side​

Answer 1

Given:

Length of diagonal of square = 12 cm

To Find:

Find area of square and length of one side

Solution:

We can solve this numerical by following steps mentioned below:

Let the square side be a cm.

And we know that all sides of square are equal..

Now, by using Pythagoras Theorem,

a² + a² = (12)²

2*a² = 144

a² = 72

a = √7204

a = 8.48 cm

Area of square = a² = 71.9104 cm²

Thus, area of square is 71.9104 cm² and length of one side is 8.48 cm
