When you have a negative in a square root. It comes out as an i. So you have i square root of 4. That comes to be 2i. The next one comes out to be 5i. Then multiply 2i times 5i. = 10 I squared then the answer is -10
82.25 square feet
Start off by multiplying 10.5 by 23.5, to get the area of her wall - 246.75 square feet. This took up 3 quartz of paint, so divide both 246.75 by 3 to find out how many square feet were painted with only 1 quartz, 82.25 square feet! :D Hope I helped!
