Answer:
<em>Alma needs $35.28 to purchase the lace for her pillow.</em>
Step-by-step 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.
