Perimeter can be found by the formula : Perimeter =  2L + 2 W

Perimeter =  2L + 2 W

Perimeter = 2(2a) + 2(a + 1) .   ← Option 4

Perimeter = 4a + 2a + 2

Perimeterr = 6a + 2                  ← Option 5

Perimeter can also be found by simply adding up all the 4 sides:
Perimeter = L + W + L + W

Perimeter = L + W + L + W

Perimeter = 2a + a + 1 + 2a + a + 1   ← Option 3

Perimeter = 3a + 1 + 3a + 1                ← Option 1


Answer: Option 1, 3, 4 and 5 are correct.
