<span>The final step in this inequality is to make x the subject. To do this, we divide both sides of the inequality by -2. Whenever we mulitply or divide by a negative number in an inequality, we must swtich the sign. So the inequality becomes -6/-2 > -2x/-2 which simplifies to x < 3. The third option is correct.Hope this helps. Let me know if you need additional help!</span>

Answer: C
Step-by-step explanation:
First, we determine the area of the wall before cutting out the door by multiplying the dimensions given.
area of wall = ( 9 ft)(5.25 ft) = 47.25 ft²
Then, we determine the area of the door by subtracting from the total area the area of the remaining wall.
area of door = 47.25 ft² - 26.25 ft² = 21 ft²
The two whole numbers that can be the sides of the door are 7 ft x 3 ft.
I believe that on the shape is length times the width which is 56
