The answer is 168 because 11 x 6 is 66 but on a triangle it would be half of that cause the formula of a triangle a = bh/2 so thats 33 and since theres 4 sides you would do 33 x 4 = 132 then 6 x 6 cause the base of the triangle = 36 and 132 plus 36 is 168

The sum of three consecutive even numbers is one hundred sixty - two.
Alenkasestr [34]

Answer:

 52

Step-by-step explanation:

Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...

  x + (x+2) +(x+4) = 162

  3x = 156 . . . . . . . . . . . .subtract 6

  x = 156/3 = 52

The smallest of the three numbers is 52.

___

I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.
