Respuesta :
If the square root is not a perfect square, then an approximation of the root often makes more sense in the context of the problem. For real-world problems, you would want an approximation, so you have an estimate of the length you are looking at.
At the time of calculating the length of the hypotenuse of a right triangle we have to approximate to determine the answer.
Length of the hypotenuse:
In the case when the square root is not a perfect square so here we take the approximation of the root so that the answer should come.
Also at each and every time the value should be determined by adding the square of base and the square of height but this does made any perfect square.
So having the non-perfect square-root number we have to approximate the answer.
