     A garden has an area of 273 ft^2 garden? Its length is 8 ft more than its width What are the dimensions of the garden?  The width of the garden is  and the length of the garden Is ?  (Simplify your answers) 
  
  Solution
Let, width be x and legnth be y
So,
y=x+8
Area=xy=x(x+8)=273
x^2+8x-273=0
273=91*3=13*21
So we can factorise the given equation as
x^2+21x-13x-273=0
x(x+21)-13(x+21)=0
x=13,x=-21
x must be positive
So, x=13, y=21
