Question

find the lengthof the side of a squarewhose area is441m²​

Answer 1

Answer:

21

Explanation:

we know the area of the square is side square so the square root of side is root 441 equal to root 3 multilply 3multiply 7 multiply 7 equal to 3multiply 7 the answer is 21

Answer 2

Answer:

Area of the square = 441 m2

Let, length of the sides are = a

As the sides of a square are equal so, we have all the sides as 'a'

So,

a2 = 441

=> a = root of 441

=> a = 21

Length of the side of a square = 21 m

Ans. 21 m

Note : Where I have written 'a2' at that place you will write a square and where I have written 'root of 441' you will give the root sign and then you will write 441
