How do you solve square give me some examples

Square roots are numbers.
if you multiply a number by itself then it is a square number. if you are looking to find a square root of a number, a square root is finding the number that was squared (multiplied by itself) to make the other number. For example,
the square root of 4 = 2
2×2 =4
Another example, square root of 64 is 8
8×8 is 64 :)

Ok but uh what do you need with?

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
