The perimeter of a triangle is the sum of the lengths of its three sides. In this case, the bottom side has a length of x + 6, the left side has a length of x, and the right side has a length of x + 4.
Therefore, the expression that represents the perimeter of Elliot's sandbox is:
(x + 6) + x + (x + 4) = 3x + 10
Elliot is building a sandbox in the shape of a triangle. A model of the sandbox is shown. Which expression represents the perimeter of Elliot's sandbox?

left side = /
the right side = x +4
x+11
3x−2
x+10
3x+10
