Question
Kumar wants to spread a carpet on the floor of his classroom. The floor is a square
with an area of 4160.25 square feet. What is the length of carpet on each side?
Hint:
find the length of the side of the square by using the area of square formula in terms of length of side.
The correct answer is: 64.5 feet
Ans :- 64.5 feet
Explanation :-
Let the length of the classroom (square) be a cm .
The we get area of class room =
So we get , 
We know that the length of side of square is length of the carpet to be used to cover it
I.e length of side of square = the required length of square carpet.
Using the long division method to find value of square root of 4160.25
The length of carpet be on each side is 
.
