three sides of a triangle are - 2x2 + 3x +1 +x2 +7 and 3x2-2x2 +3
wht is its perimeter?
PLS GIVE STEPS ALSO
Answer :
Given : Sides of triangles are - 2 x2 + 3 x + 1 , x2 + 7 and 3 x2 - 2 x 2 + 3
We know perimeter of triangle = Sum of all three sides
So,
Perimeter of given triangle = - 2 x2 + 3 x + 1 + x2 + 7 + 3 x2 - 2 x 2 + 3 = 3 x + 11 ( Ans )
