Question

I need help understanding this please

Answer 1

Explanation:

324 square centimeters can easily be broken down into the multiplication expression 18 x 18.

since Alma's lace border will follow that area, at 98 cents for every 2 centimeters, we can do as such:

`18/2=9\\ [there are 9 sets of two centimeters on each side, meaning that our equation would look something like this:]\\ 9(0.98)^2\\ [which would equal something around] 8.6436\\\\ [that] 8.6436\\ [is the total price of the area the lace takes.]\\`

This doesn't necessarily answer your question, but i hope i did a good job explaining! if im wrong, please, correct me!

Answer 2

Alma needs $35.28 to purchase the lace for her pillow.

Explanation:

If it is a square, the length and the width would be the same. You have to take the square root of the area, so the square root of 324 is 18. Now, we know that the length is 18 cm and the width is also 18 cm. If she's selling every 2 centimeters for 98 cents, you have to find the total amount of centimeters the pillow has, so 18*4 (the 4 comes from the number of sides on the pillow)=72.

Now divide that answer by the 2 lace centimeters she will get. (72/2=36 cm).

Now multiply that by 98 cents, the cost. (36*0.98=35.28).

So Alma needs $35.28 to purchase the lace for her pillow.
