I posted this the other day but no one responeded. Yes, I am looking for the steps and a answer because I can not get it.
Question: Area of Painting: A rectangular painting with a width of x centimeters has an area X^2 +50x square centimeters. Find a binomial that represents the length.

X^2 +50x factors and
= x(x + 50)
clearly, x must be a positive number, so clearly x+50 is larger than x
Usually, in talking about length and width, the length is the larger of the two dimensions, isn't it ?
So, what do you think? 
To be honest, I could not figure out this problem. I don't know why I am so confused..

Area = width x length
X^2 +50x = x(x+50)
so x must be the width
x+50 must be the length 
How do you multiply fractions like 15 x 25 please help me with my home work please.
