Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters

Answer:
16 seconds
Step-by-step explanation:
You want to find t such that h(t) = 0
h(t) = -16t^2 +4096 . . . equation for height
0 = -16t^2 +4096 . . . . .equation for height = 0
16t^2 = 4096 . . . . add 16t^2
t^2 = 256 . . . . . . . divide by 16
t = 16 . . . . . . . . . . . take the positive square root
It will take 16 seconds for the camera to hit the ground.

Answer:
the length of the piece of rope in meters is 22
Step-by-step explanation:
The computation of the length of the piece of rope in meters is shown below:
= 2πr
= 2 × 3.14 × 3.5m
= 21.98
= 22 meters
Hence, the length of the piece of rope in meters is 22
