Answer:25 ft

Step-by-step explanation:

This triangle is an isosceles triangle (2 sides are congruent), we see this because is two angles of a triangle is congruent, then the two opposite sides are congruent.

From this information, we can say that 2x-1 = x+4

Add 1 on both sides to get 2x=x+5

Then minus x on both sides to get x=5


Next, plus x into the two equations separately.

1) 2 times 5-1

2 times 5 is 10

10-1=9


2) 5+4=9


Finally, add the sides together to get the answer.

9+9+7=25ft

Hope this helped!
