If length and breadth of a rectangle is 'x' and 'y' respectively, then the perimeter of the rectangle is ____.
2x + 2y
As per the question
Length of a rectangle = x
Breadth of a rectangle = y
Perimeter of rectangle = 2 (length + breadth)
On substitutng the values we get:
Perimeter of rectangle = 2 × (x+y)
Perimeter of the rectangle = 2x+2y
