Area of a painting A rectangular painting with a width of x centimeters has an area of x^2 + 50x square centimeters. Find the binomial that represent the length

Answer 1

area= length*width
x^2+50x=l*x

x+50=l

Answer 2

area= length*width

x^2+50x=l*x Divide with x

(x^2/x)+50x/x=l*x/x

x+50=l

l=x+50
