Answer:
138 square centimeters
Step-by-step explanation:
You can find the area by splitting up the shape into pieces and adding it all together, and you get 138 square centimeters.
R = Rate of gasoline by automobile = 35 mi/gal
it is given that , 1 kilometer = 0.6214 miles
and 1 gallon = 3.78 liter
so
R = 35 (miles/gallon) (1 kilometer/0.6214 miles) (1 gallon/3.78 liter)
R = (35) (1/0.6214) (1/3.78) (miles x 1 kilometer/1 miles) (1 gallon/(1 gallon x 1 liter))
R = 14.9 kilometer/liter
