The expression that represents the perimeter of the rectangle is 22b + 22 cm.
To find the perimeter of the rectangle, sum the lengths of all its sides. With two sides measuring (3b + 5) cm in width and two sides measuring (8b + 6) cm in length, the expression representing the rectangle's perimeter is obtained by combining these dimensions:
Perimeter = 2 * (3b + 5) + 2 * (8b + 6)
Simplifying this expression, we get:
Perimeter = 6b + 10 + 16b + 12
Combining like terms, we get:
Perimeter = 22b + 22
So, the expression that represents the perimeter of the rectangle is 22b + 22 cm.
