Question 335799: Hello! I'm from an Asian Country and I'm not good at English. So sometimes I get confused with some word problems. Please help me with this word problem.
" The length of a rectangle is x+2 and width is x-1 and a square has a length of each side is x. The area of the rectangle has shown exceeded the area of the square by 2 square centimetre. Find x."
So I write the equation as (x+2) (x - 1) = (x) (x) + 2
Please correct me if my equation is wrong. (What my problem is the word "exceeded by 2 sq cm", so I confused with two x square or x square plus two) Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! length of a rectangle is x+2.
width of the rectangle is x-1.
length of the side of a square is x.
The area of the rectangle exceeds the area of the square by 2 square centimeters.
Find x.
exceeds means "is greater than"
the area of the rectangle is equal to length * width = (x+2) * (x-1).
the area of the square is equal to side * side = x * x = x^2.
Since the area of the rectangle exceeds the area of the square by 2 square centimeters, then the equation would be:
(x+2) * (x-1) = x^2 + 2
I believe you have the equation right.
Solving this problem, you get:
x^2 + x - 2 = x^2 + 2
Subtracting x^2 from both sides of the equation and adding 2 to both sides of the equation gets:
