The polynomial expression that represents the perimeter of the rectangle is 10a + 6. A
How to find the perimeter of a rectangle
To find the perimeter of a rectangle, add up the lengths of all four sides. In this case, the width of the rectangle is given as (3a + 4) and the length is given as (2a - 1).
The perimeter can be calculated using the formula:
Perimeter = 2 * (length + width)
Substitute the given expressions for length and width into the formula, we get:
Perimeter = 2 * ((2a - 1) + (3a + 4))
Simplifying the expression:
Perimeter = 2 * (5a + 3)
Perimeter = 10a + 6
Therefore, the polynomial expression that represents the perimeter of the rectangle is 10a + 6.
