Question

If (2x - 3y) units, (7x + y) units, (x + 12y) units and (3y - 4x) units are the lengths of the sides of
a quadrilateral, then find the perimeter of the quadrilateral.
​

Answer 1

Answer:

7x + 13y

Step-by-step explanation:

$perimeter \: of \: a \: quadrilateral \: = sum \: of \: all \: 4 \: sides \\ sum \: of \: all \: sides \: = (2x - 3y) + (7x + y) + (x + 12y) + (3y - 4x) \\ 2x - 3y + 7x + y + x + 12y + 3y - 4x \\ 2x + 7x + x - 4x - 3y + y + 12y + 3y \\ 7x + 13y \\ \\ hope \: this \: will \: help \: you$
