A piece of wire of length 1meter is cut into two parts and each part is bent to form a square. The total area of the two squares formed is 325 centimetre Square.
1, Given that one of the pieces is x cm long, find the area of the square formed from this piece in terms of x.
2,Find the area of the square formed by the remaining piece in terms of x.
3,Determine the possible values of x.
If one part is x , the other part will be (100-x)cm
One side of first square will be x/4 and the side of other square will be %28100-x%29%2F4


Area of first square = %28x%2F4%29%5E2


Area of other square = %28+%28100-x%29%2F4%29%5E2
Sum of their areas

%28x%2F4%29%5E2 + %28+%28100-x%29%2F4%29%5E2= 325
Simplify
%28x%5E2%2F16%29+%2B+%28%2810000-200x+%2Bx%5E2%29%2F16%29+++=325


+%282x%5E2+-200x+%2B10000%29%2F16++++=325


+2x%5E2+-200x+%2B10000++++=16%2A325

+2x%5E2+-200x+%2B10000++++=5200

+2x%5E2+-200x+%2B+4800=0

+x%5E2+-100x+%2B+2400=0

Solve for x
x=40 or 60
