A daredevil jumps off the CN Tower and falls freely for several seconds before releasing his parachute. His height, h, in meters, t seconds after jumping can be modeled by: h(t) =-4.91? + + + 360 before he released his parachute; and h(t) = -4t + 142 after he releases his parachute. How long after he jumped did he release his parachute?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
