Well, to calculate the area, we would simply do length times width and we would get our area.
Area = Length * Width
Area = 12cm * 4cm
Area = 48cm squared.
So, in conclusion, the area is 48 cm squared.
PEMDAS so you do 3*4 which equals 12, then you add 8=20 20/2=10
100 + 8d = 300; d = 25; The kitten will triple its weight in 25 days
-6 and -4 are your inputs -2 and 7 are your outputs
