(Tell whether each expression would give you the area or the perimeter of the rectangle)

1.)XY

4) y + 2x +y

the area of a rectangle is

length times width

the perimeter of a rectangle is twice the length + twice the width

Nina -- or whoever you are --

Damon, Anonymous, and I have all tried to help you on this simple question.

Please don't post it again without telling us what you don't understand about our responses.

i don't get this because if the first box says XY how do i know what to multiply since those are LETTERS not NUMBERS so how do i solve it then?

Thank you for clarifying your confusion.

Your question asks which expression to use. It doesn't ask you to solve the problem with real numbers.

1) xy means two different unknown numbers multiplied together.

4) y + 2x + y means you add 2 times an unknown and 2 times another unknown.

To determine whether each expression gives you the area or the perimeter of the rectangle, we need to understand the formulas for calculating the area and perimeter of a rectangle.

1. "XY": This expression does not correspond to either the area or the perimeter of a rectangle. It appears to be a combination of the variables X and Y without any specific meaning in the context of rectangle geometry.

2. "4": This expression does not have any variables or dimension references, so it does not represent either the area or the perimeter of a rectangle. It is simply the number 4.

3. "y + 2x + y": This expression represents the perimeter of a rectangle. The formula to calculate the perimeter of a rectangle is given by 2 * (length + width), where "length" and "width" refer to the sides of the rectangle. In this expression, "y" represents one side of the rectangle, "2x" represents the other side (as the width is typically twice as long as the length), and "y" represents the remaining side. Adding the three sides together gives us the total perimeter.

Overall, expressions 1 and 2 do not correspond to the area or the perimeter of a rectangle, while expression 3 represents the perimeter of a rectangle.
