The perimeter of a parallelogram is 40 cm, and its two sides are 3: 2. what is its big side

1. Let’s denote one part by x.

2. Determine the length of the shorter side of the parallelogram:

3 * x = 3x cm.

3. Find out what the large side of the parallelogram is equal to:

2 * x = 2x cm.

4. Let’s compose and solve the equation:

(3x + 2x) * 2 = 40;

5x * 2 = 40;

10x = 40;

x = 40: 10;

x = 4.

5. One part is equal to x = 4.

6. What is the length of the longer side of the parallelogram?

3 * x = 3 * 4 = 12 cm.

Answer: The large side of the parallelogram is 12 cm.
