Davis knows that the area of his square-shaped bag is 810 cm squared. What is the length of any side of the bag?

All sides of a square are equal in length, therefore in order to find the length of one of the sides you must determine the square root of 810. This is because, to determine the area, you square the length of a side.

√810 = 28.5 cm

Therefore the length of one side is 28.5cm

As the formula of area of square is X^2 where x is length of any side so here X^2 = 810 so the anawer will be √810which is equal to 28.5
