It is A=s^2
area = length of side times itself If you have square with side length 3, area is 3x3, 9 square units

You cannot directly convert, square metres represents area where as metres simply represent distance. This is very basic maths. If the area was a square, you can find the area in square metres by multiplying the width in metres by the height.
It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
If the side of the square is X then we are going to have 4x=x2 From this equation we get x=4
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
The side length would be 7. It is 7 because when you find the area of a square, the equation is s2=A. (s=side length A=area). When you only have the area of a square and you want to find the side length, you replace "A" with the area (in this case 49). Then you would have s2=49. To find the side length you would square both sides of the equation. √(s2)=√(49). 49 is perfect square so it's not too difficult to find out the answer. You would be left with s=7. Therefore the side length is 7. Step by step: s2=A s2=49 inches2 √(s2)=√(49) s=7 inches2
