Step-by-step explanation:
See picture for steps :)
let "L" represent the length of the rectangle
let "W" represent the width of the rectangle
Area of the rectangle = LW
68= LW --------eqn 1
Area of a square = L/2 ×L/2
34= L^2/4
136=L^2
L= 11.67
From eqn 1 , W=68/L
W=68/11.6619
W=5.83
7(3 + 9) = 7(3) + 7(9) = 21 + 63
Answer:
262.8 Liters per year
Step-by-step explanation:
10 drops per min mean 0.5 mL per minute
<em><u>How many minutes are there in a year??</u></em>
60 minutes in 1 hour
24 hours in 1 day
365 days in 1 year
So,
60*24*365 = 525,600 minutes per year
0.5 mL per minute and in 525,600 minutes, that is:
0.5 * 525,600 = 262,800 mL per year
Converting this to liters (1000 mL is 1 Liter):
262,800/1000 = 262.8 Liters per year
