<u>Formula Evaluation</u>
Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.
Formulas are usually expressed as mathematical operations that connect one or more variables.
The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula
We are given the values of
Thus the perimeter is
Since we know that a number is divisible by 3 if the sum of all digits is divisible by 3.
Let us check which digits will make 371? divisible by 3.
11 is not divisible by 3.
Now let us check other digits as well.
12 is divisible by 3.
15 is also divisible by 3.
18 is divisible by 3 as well.
Therefore, 1, 4 and 7 in tenth place will make our number divisible by 3 and our numbers will be 3711, 3714 and 3717.
