ABCDE and FGHIJ are regular pentagons, with FGHIJ being the larger of the two. One side of pentagon ABCDE is 4 units long. If the ratio of the perimeters of the two pentagons is 2:3, how many units long is a side of pentagon FGHIJ?

Answer :

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.
