A retangular field covers 2400m^2. its lengh is 50m longer than it's width what's its with
Let the width of the field = x
So, the length of the field = x+50
We know,
area of rectangle = length*width
or 2400 = x*(x+50)
x^{2}+50x = 2400
x^{2}+50x-2400 = 0
(x+80) (x-30) = 0
So, x = -80 or x = 30
Since we can't have negative width, the answer is 30
Hence the width of the field is 30m
