Answer:
Step-by-step explanation:
as mode is 45 ,two of three is 45
i assume x =y=45
now (41+46+45+45+z)/5=50
177+z=50×5=250
z=250-177=73
so x=45
y=45
z=73

l = 60 feet
Step-by-step explanation:
use the equation and plug in the width(40 feet) for w and perimeter(200 feet) for p.
200 = 2l + 2(40)
then solve for l
200 = 2l + 80
120 = 2l
l = 60 feet
