Answer 2

Perimeter =
`3x^2+37x-4` feet

Explanation:

The perimeter of a triangle is sum of all the three sides. To get the perimeter (the expression) we add the expressions of all the three sides and do algebra:

12x + 15x + 4 + 10x + 3x^2 - 8

3x^2 + 12x + 15x + 10 x + 4 - 8 [rearranged]

3x^2 + 37x - 4

Hence, the perimeter is
`3x^2+37x-4` feet
