⚫In this question, we have to find the length of the side of the square

So,

▶Length of side of square = ?

▶Area of a square = 441m²

▶▶As we know that the formula to find out area is

area = side × side

area = side²

▶If we send square to other side then the formula will be

√area = side

side = √area

▶By putting values,

side = √441

side = 21

⏩⏩So, the length of the side of the square will be 21m.
