Width = 7n - 1.5

Length = 1.5n + 8

Formula

Perimeter = 2(length) + 2(width) or length + length + width + width

Substitution

Perimeter = 7n - 1.5 + 7n - 1.5 + 1.5n + 8 + 1.5n + 8

Simplification

Perimeter = (7n + 7n + 1.5n + 1.5n) + (-1.5 - 1.5 + 8 + 8)

Perimeter = 17n + (-3 + 16)

Result

Perimeter = 17n + 13
