Answer:
square foot per hour
Step-by-step explanation:
The total area covered = 34 square foot
Time taken = 12 hours
This implies that it takes 12 hours to cover 34 square foot.
Using proportionality,

Answer:
Amount of hay in first barn = 90 tons
Amount of hay in second barn song = 30 tons
Step-by-step explanation:
Let the amount of hay in second barn be x, then hay in first barn will be 3x.
20 tons of hay was removed from first barn and ws added to second barn.
Now, the amount of hay in first barn = 3x -20
Amount of hay in second barn = x+20
The equation now formed is:
x+20 = (3x-20)
7x+14 = 15x -100
-8x = -240
8x = 240
x = 30
3x = 90
Amount of hay in first barn = 90 tons
Amount of hay in second barn song = 30 tons
This is the formula for finding the area of a trapezoid
