Elaine purchased 4.5 yards of lace trim from her local fabric shop. She has a circular tablecloth that is 54 inches in diameter and a square tablecloth that is 40 inches on each side. Can she trim either tablecloth?

Yes

I don't know that's why I was having trouble understanding this question

To determine whether Elaine can trim either tablecloth with the 4.5 yards of lace trim, we need to calculate the perimeter of each tablecloth.

For the circular tablecloth:
- The diameter is given as 54 inches, so we can find the radius by dividing it by 2: 54 / 2 = 27 inches.
- The formula to calculate the circumference (perimeter) of a circle is: C = 2πr (where π is approximately 3.14).
- Plugging in the value of the radius, the circumference is: C = 2 * 3.14 * 27 = 169.56 inches.

For the square tablecloth:
- The length of each side is given as 40 inches.
- The formula to calculate the perimeter of a square is: P = 4s (where s is the length of a side).
- Plugging in the value of the side length, the perimeter is: P = 4 * 40 = 160 inches.

Now, let's see if Elaine has enough lace trim for each tablecloth:
- For the circular tablecloth, the lace trim needs to be at least as long as the circumference. If the lace trim is 4.5 yards, we need to convert yards to inches by multiplying by 36 (since there are 36 inches in a yard): 4.5 * 36 = 162 inches. Elaine has enough lace trim for the circular tablecloth.
- For the square tablecloth, the lace trim needs to be at least as long as the perimeter. Since the perimeter is 160 inches, and Elaine has 162 inches of lace trim, she has enough for the square tablecloth as well.

Therefore, Elaine can trim both the circular and square tablecloths using the 4.5 yards of lace trim she purchased.

What is the circumference of the circular tablecloth?

What is the perimeter of the square table cloth?
