A rock climber ascends 18 3/4 feet to the top of a rock ledge. The climber descends 8 1/4 feet and takes a break on a rock outcrop. Write and evaluate an addition expression to show how much farther the rock climber must descend to reach the original level. Fast please!!!

50.6

step-by-step explanation:

it would be 3 ÷by 6 because the number on each side

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 : )
