Final answer:
A side of pentagon FGHIJ is 6 units long.
Explanation:
Let's assume the length of a side of pentagon FGHIJ is x units.
The perimeter of pentagon ABCDE is 5 times the length of its side, which is 5 * 4 = 20 units.
The perimeter of pentagon FGHIJ is 5 times the length of its side, which is 5 * x = 5x units.
Given that the ratio of the perimeters is 2:3, we can set up the equation 20/5x = 2/3.
Cross-multiplying gives us 3 * 20 = 5x * 2.
Simplifying, we have 60 = 10x.
Dividing both sides by 10, we find x = 6.
Therefore, a side of pentagon FGHIJ is 6 units long.
