Please answer this correctly

9.5 ft

Step-by-step explanation:

The perimeter is equal to

P =2(l+w)

29.6 = 2(5.3+z)

Divide each side by 2

29.6 /2 =2/2(5.3+z)

14.8 = 5.3 +z

Subtract 5.3 from each side

14.8-5.3 = z

9.5 =z

Z=9.5

Step-by-step explanation:

Perimeter(of a triangle)=2(5.3+z)

29.6=10.6+2z

2z=29.6-10.6

2z=19(then divide both sides by 2 to find the value of z)

z=19/2

z=9.5 ft

To check your answer

29.6=2(5.3+9.5)

29.6=2(14.8)

29.6=29.6 so your answer is correct.
