Question

solve this question by rule steply

Answer 1

Perimeter =sum of all sides
therefore
by sum we have
9x^2+x-5

Answer 2

perimeter = sum of all sides
perimeter = $( 3x^{2} -3 x+1 )+(4 x^{2} +4 x-2)+(2 x^{2} -3)$
perimeter = $3 x^{2} -3 x+1+4 x^{2} +4 x-2+2 x^{2} -3$
perimeter = $9 x^{2} + x-4$
