Answer 1

Answer:

14x + 2y

Step-by-step explanation:

Given,

Dimensions of the rectangle = 5x - y, 2(x+y) or 2x + 2y

Therefore,

Perimeter of the rectangle = 2 (l+b)

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

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

= 2 (7x + y)

= 2 × 7x + 2 × y

= 14x + 2y (Ans)

Answer 2

Answer:

14x+2y

Step-by-step explanation:

Perimeter of rectangle = 2(sum of its a adjacent sides)

side = 5x-y and 2(x+y)=2x+2y

perimeter = 2(5x-y+2x+2y)

= 10x-2y+4x+4y

= 14x+2y

so, perimeter of rectangle= 14x+2y
