Perimeter of Parallelograms Worksheets - Free Printable

This is a worksheet for calculating the perimeter of parallelograms. The perimeter of any polygon is the sum of the lengths of all its sides. For a parallelogram, opposite sides are equal in length. Therefore, the formula for the perimeter (P) of a parallelogram is:

P = 2 × (length + width)

or

P = 2 × (side1 + side2)

I will calculate the perimeter for each of the 9 parallelograms shown.

Problem 1

- Sides: 4 ft and 12 ft
- Perimeter = 2 × (4 ft + 12 ft) = 2 × 16 ft = 32 ft

Problem 2

- Sides: 2 in and 10 in
- Perimeter = 2 × (2 in + 10 in) = 2 × 12 in = 24 in

Problem 3

- Sides: 9 yd and 6 yd
- Perimeter = 2 × (9 yd + 6 yd) = 2 × 15 yd = 30 yd

Problem 4

- Sides: 8 in and 4 in
- Perimeter = 2 × (8 in + 4 in) = 2 × 12 in = 24 in

Problem 5

- Sides: 17 yd and 9 yd
- Perimeter = 2 × (17 yd + 9 yd) = 2 × 26 yd = 52 yd

Problem 6

- Sides: 20 ft and 14 ft
- Perimeter = 2 × (20 ft + 14 ft) = 2 × 34 ft = 68 ft

Problem 7

- Sides: 15 yd and 7 yd
- Perimeter = 2 × (15 yd + 7 yd) = 2 × 22 yd = 44 yd

Problem 8

- Sides: 11 ft and 18 ft
- Perimeter = 2 × (11 ft + 18 ft) = 2 × 29 ft = 58 ft

Problem 9

- Sides: 5 in and 13 in
- Perimeter = 2 × (5 in + 13 in) = 2 × 18 in = 36 in

3) 30 yd
4) 24 in
5) 52 yd
6) 68 ft
7) 44 yd
8) 58 ft
9) 36 in
