C.21 ft x 48 ft
because you multiply 7 by 3 and 12 by 3 and that is what it is

. It would be an indirect proof that is not an acceptable form of proof. This is because this type proof is not used by any problem (B) is the answer
29.98+ 6.44 = 36.42 (cost with out the discount)
36.42/3 = 12.14
Answer-
12.14
All you've got to do is multiply both 13 and 20 by 5 so the fractions would be 65/100. Since you're trying to convert it into a decimal, you would move the decimal point 2 units to the right. This will result in the answer : 0.65.
Changing 13/20 would be 0.65
