Question

How to find length of diagonal of square of side 15?

Answer 1

Answer:

Step-by-step explanation:

so the length of each side of the square is 15 cm.

since we know that to find the hypotenuse, we need two sides and then we can find the other diagonal.

so the answer will be

AB square + BC square= CA square

therefore,

1. 15 square+ 15 square= CA square
2. 225+225= CA square
3. 450= CA square

therefore CA is 21.2cm

therefore, if you want to calculate the length of the diagonal in a square, one way can be by using the hypotenuse method.

there are other ways also to find this answer but this seems to be most appropriate.

hope this helps you.

thank you
