My answer is 30 ft. am I correct.
What do you find for BF ?
Use the Pythagorean theorem : hypotenuse˛=side˛+otherside˛
Then, you know that the perimeter will be 5 times BF, as it is a regular pentagon.
For the area, it's 5 times the area of SEF.
You have SR, you have EF, so what is the area of this triangle ?
