The answer is A
if you add them all together, there are 15 employees, and only 5 have at least 10 years of experience. 5/15 simplifies to 1/3
Let, width = x
Length = 3x
It is given that, 3x * x = 300
3x² = 300
x² = 300 / 3
x = √100
x = 10
& 3x = 3(10) = 30
Perimeter = 2(l + w)
P = 2(10 + 30)
P = 2(40) = 80
In short, Your Answer would be 80 Yards
Hope this helps!
The perimeter because the fence goes AROUND the yard, not in it.
P = 2w + 2l
P = 2(60) + 2(20)
P = 120 + 40
P = 160
Charlene needs 160 meters of fencing material.
