Answer: The expression for the perimeter of the rectangle =14x-8.
Explanation:
Given: Expression for length of rectangle = 5x-3
Expression for width of rectangle = 2x-1
We know that,
Perimeter of rectangle = 2 (length + width)
Then, perimeter of rectangle = 2(5x-3+2x-1)
= 2(5x+2x-3-1) [Combine like terms]
= 2 (7x-4)
= 14x -8
Hence, the expression for the perimeter of the rectangle = 14x-8
