The length of a rectangular room is 9 feet greater than its width. Which of the following equations represents the area (A) of the room?
A=9x
A=2x+2(x+9)
A=x(x+9)
A=x+(x+9)
Correct Answer : C
we are asked to find the area of the room from the given information.
The first step is to find equation relating the length of the room to its width. If we let the width of the room to be x. Then,
Width of the rectangle= x
Length of rectangle = (x+9)
Area of the rectangle, A= Length*width = (x+9)*x
A=x(x+9)
Therefore, the area of the rectangular room is x(x+9).
