The number of observations is 15
Answer:
Length =40 ft.
width. = 8 ft.
Step-by-step explanation:
If The length is five times the width , then
width = w
length = 5w
Perimeter of Rectangle = 2( l+b)
2(5w+w)= 96
2( 6w) = 96
12 w= 96
w = 96/12
w= 8ft.
length = 5(8)
= 40 ft
Answer:226.2
Step-by-step explanation
Lateral= 2πrh
H=12
R=3
2*π*3*12=226.19
