Find the perimeter of the following rhombuses. Choose your answer inside the box below.

1. Side = 8 cm
2. Side = 13 cm
3. Side = 20 cm
4. Side = 6 cm
5. Side = 15 cm

A. 60 cm
B. 52 cm
C. 80 cm
D. 24 cm
E. 32 cm

To find the perimeter of a rhombus, you need to know the length of one of its sides. Since all sides of a rhombus are equal, the formula for the perimeter P is:
P = 4 × side length
Let's calculate the perimeter for each given side length:

For a side length of 8 cm: P = 4 × 8 = 32 cm This matches option E: 32 cm.

For a side length of 13 cm: P = 4 × 13 = 52 cm This matches option B: 52 cm.

For a side length of 20 cm: P = 4 × 20 = 80 cm This matches option C: 80 cm.

For a side length of 6 cm: P = 4 × 6 = 24 cm This matches option D: 24 cm.

For a side length of 15 cm: P = 4 × 15 = 60 cm This matches option A: 60 cm.


In summary, the perimeters corresponding to the given side lengths are:

8 cm: 32 cm (E)
13 cm: 52 cm (B)
20 cm: 80 cm (C)
6 cm: 24 cm (D)
15 cm: 60 cm (A)

These calculations use the formula for the perimeter of a rhombus and directly correspond to the multiple-choice options provided.
