Question 975306: I need help in this situation about solving quadratic equation by extracting square roots it goes like this:
Mr. Cayetano plans to install a new exhaust fan on his room's square-shaped wall. He asked a carpenter to make a square opening on the wall
where the exhaust fan will be installed.The square opening must have an area of 0.25 meters squared.
And here's the follow up question:
How are you going to represent the length of a side of the squared-shaped wall?HOW About its area?

You can put this solution on YOUR website!
x, the length of a side of the square.
x%5E2=0.25
x=sqrt%280.25%29

The description seems to be asking about the square but empty opening area of the opening.
x=sqrt%285%5E2%2F10%5E2%29
x=5%2F10
x=1%2F2

Area is same as what is given.
