The pentagon in washington dc is immense in size, with each outside wall 921 feet in length. what is the perimeter of the pentagon?

The perimeter of the Pentagon would be 4,605 feet. Add 921, 5 times because a pentagon has 5 sides. When you add 921, 5 times, you should get 4,605 feet.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

hope it is correct if not i'm srry i tried to
