Problema Solution
The dimensions of a certain computer monitor screen are such that its length is 2 inches more than its width. if the length is increased by 1 inch while the width remains the same the area is increased by 10 square inches. what are the dimensions of the screen?
Answer provided by our tutors
Let width is x inches.
So, Length=(x+2) inches.
So, Area is x(x+2).
When length is increased by 1 and width remain same then area is (x+2+1)(x).
So, x(x+2)+10=(x+3)x
x^2+2x+10=x^2+3x
x=10
So, width=10 inches and length=12 inches.
