Aschool wants to build a rectangular playground that will have a diagonal length of 75 yards. how wide can the playground be if the length has to be 30 yards?

the 3rd on is correct

step-by-step explanation:

step-by-step explanation:

y= -2x+4, have a great day

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 : )
