(2 points)height: $6\frac{1}{2}$ feet (or $\frac{13}{2}$ feet)2. find the area of the door. leave your answer as an improper fraction. (2 points)

2. Explanation

   Step1: Convert wall dimensions to improper fractions

   Wall width: $11\frac{1}{2} = \frac{23}{2}$ feet, Wall height: $8\frac{1}{2} = \frac{17}{2}$ feet

   Step2: Calculate total wall area

   $\text{Area}_{\text{wall}} = \frac{23}{2} \times \frac{17}{2} = \frac{391}{4}$ square feet

   Step3: Convert door dimensions to improper fractions

   Door width: $3 = \frac{3}{1}$ feet, Door height: $6\frac{3}{4} = \frac{27}{4}$ feet

   Step4: Calculate door area

   $\text{Area}_{\text{door}} = \frac{3}{1} \times \frac{27}{4} = \frac{81}{4}$ square feet

   Step5: Calculate area to paint

   $\text{Area}_{\text{to paint}} = \frac{391}{4} - \frac{81}{4} = \frac{310}{4} = 77.5$ square feet

   Step6: Compare to paint coverage

   Paint covers 100 square feet, $77.5 < 100$

3. Final answer
   1. $\frac{391}{4}$ square feet
   2. $\frac{81}{4}$ square feet
   3. Yes, she has enough paint left.
