Answer 2

Perimeter of a Parallelogram

To find the sides of a parallelogram when the perimeter is known and one side is 3 dm longer than the other, we can use the formula for the perimeter of a parallelogram.

The formula for the perimeter of a parallelogram is:

Perimeter = 2(a + b)

Where: - a is the length of one side of the parallelogram - b is the length of the adjacent side of the parallelogram

Given that the perimeter is 144 cm and one side is 3 dm (30 cm) longer than the other, we can set up the following equation:

144 = 2(a + (a + 30))

Simplifying the equation:

144 = 2(2a + 30)

72 = 2a + 30

2a = 72 - 30

2a = 42

a = 42 / 2

a = 21

So, one side of the parallelogram is 21 cm.

Since one side is 3 dm (30 cm) longer than the other, the other side can be found by subtracting 30 cm from the length of the first side:

b = a - 30

b = 21 - 30

b = -9

However, a negative length does not make sense in this context. Therefore, it is not possible to find the lengths of the sides of the parallelogram given the information provided.

Please double-check the given information or provide additional details if available.
