17x6=102 total pets sold over 6 days
19+21+6+17+11=74 total pets sold within the first 5 days
102-74=28 pets sold on the 6th day
Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
