We know that a rectangle has two widths that are equal and two lengths that are equal. One width is 22, so the other one is also 22.
If you wanted to find the lengths, you would add both widths together (same as multiplying a width by two) and add that to the two lengths equaled to the perimeter.
So, 22 * 2 + 2x = perimeter of rectangle. We added all four sides together.
We know that the perimeter is at least 165, so 22 * 2 + 2x = 165. Here's the twist. They want the most minimum possible length. So, what answer choice gives you 165 or less for the most minimum or smallest length while still getting to 165? That is D. 22 * 2 + 2x < = 165. Hope this helped!
The answer is A. The other guy who answered it is right untill the end. Hes saying that the perimeter is less then 165. When the question clearly says that 165 has to be the minimum length for the perimeter. Hope this strightens things out for ya.
If Vanessa wants to know hoy the car's maintenance costs change as the distance increases, she is analysing the cost of maintaining the car (wich is expressed in dollars , $), when the distance increases (which is measured in miles or metres, or some other distance measure).
Then, the appropiate units of measure for this problem are dollars (to represent the cost of maintenance) and miles (to represent the distance the car travels).
