the sides of the quadrilateral are 2x-1,+x+%2B+3, 3x+%2B+1, and x+-1
double the length of each side:
2%282x-1%29,+2%28x+%2B+3%29, 2%283x+%2B+1%29, and 2%28x+-1%29
4x-2,+2x+%2B6, 6x+%2B+2, and 2x+-2
then find an expression for the perimeter of the new figure:
the perimeter is equal to the sum of all sides; so, we have
%284x-2%29%2B%282x+%2B6%29%2B%286x+%2B+2%29%2B%282x+-2%29
4x-2%2B2x+%2B6%2B6x+%2B+2%2B2x+-2
4x%2B2x+%2B2x%2B6x+%2B6%2Bcross%28+2%29-cross%282%29+-2
14x+%2B6+-2
14x+%2B4
