Question

1. ping is sewing a square tablecloth. the table she wants to cover is 5.5 feet on each side and she wants it to hang over on each side 9 inches. how many square feet of fabric will ping need?

Explanation:

Step1: Convert inches to feet

Since 1 foot = 12 inches, 9 inches = $\frac{9}{12}= 0.75$ feet.

Step2: Calculate the side - length of the tablecloth

The side - length of the table is 5.5 feet and it hangs over 0.75 feet on each side. So the side - length of the tablecloth $s=5.5 + 0.75+0.75=7$ feet.

Step3: Calculate the area of the tablecloth

The area $A$ of a square is $A = s^2$. Substituting $s = 7$ feet, we get $A=7^2 = 49$ square feet.

Answer:

49 square feet
