Given the original dimensions above which is 3ft and 4ft, the area of the painting on a canvass would be 12ft. Since Linda wants to double the area of the display model, this makes the doubled area 24ft. So in order to get this area, Linda should add 1.4 feet to both the length and the width, making the dimensions 4.4ft and 5.4ft. Multiply both and you get 23.76ft or to round it off, 24 feet. Hope this answers the question.
It will have 2 solutions because, if you take out the (-) it will be a whole diffrent answer!
Step-by-step explanation:
step 1. c = 14(pi) m = 43.96m
step 2. c = 2(pi)(3) = 6(pi) m = 18.84in
(-6)/2=-3 -3+(-6)=-9 so the answer is -9
