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:
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
