The sides of a triangular lot are represented by x, 2x, and 3x + 2. Find each side if the perimeter is 362 feet.

To find perimeter, you add up all the sides.

So, your equation would be:

x+2x+3x+2=362

Combine like terms:

6x+2=362

Solve to get x by itself by subtracting 2.

6x=360

Divide by 6

x=6

To find each side, substitute 6 in for x for each of the expressions, x, 2x, and 3x+2

Side one would be 6 feet

Side two would be 12 feet because 6(2) is 12

Side three would be 20 feet because 6(3) is 18 and adding 2 would give you 20.

O my, x=60, not 6.. My fault for overlooking that.

The three sides would be,

60

120

182

*Sorry again
