Answer 2

Answer:

28 x + 10 y

Step-by-step explanation:

We know that,

The given figure is a rectangle

We also know that,

Perimeter of a rectangle = 2 ( l+b )

where l = (7x-2y) , b = 7(x+y)

That is,

2[ (7x-2y)+7(x+y) ]

2[ 7x-2y + 7x+7y ]

2[ (7x+7x) + (-2y + 7y) ]

2[ 14x + 5y ]

= 28x + 10y

Therefore,the perimeter of the given figure is ( 28x + 10y )
