Question

The length of a rectangle is repesented by (5×-3) and the width is repesented by (2×-1) write an expression for the perimeter of the rectangle

Answer 1

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
