Question

9. Find the perimeter of given quadrilateral ABCD​

Answer 1

Answer:

2(5x-y)+2×2(x+y)

10x-2y+4x+4y

perimeter=14x+2y

Answer 2

Answer:

the perimeter of quadrilateral is 14x + 2y

Step-by-step explanation:

we know that the perimeter of any quadrilateral

sum of all sides

then ,

$(5x - y) + 2(x + y) + (5x - y) + 2(x + y)$

we can written above in also short form

$2(5x - y) + 2(2x + 2y)$

$2(5x + 2x + 2y - y)$

$2(7x + y)$

$14x + 2y$
