I think I know what you're asking but I'm not 100% but there would be no equal sides or equal angles. Hope this helps!
Car 1 consumes 30 gallons of gas.Car 2 consumes 20 gallons of gas.
You can put the 2 circles together to get 1 circle
so basically we just find
area of rectangle taht is 8ft by 18ft
and area of ciecle with disameter of 8
area rectangle=18 times 8=144 square feet
area of ciecle=pir^2
d/2=r, 8/2=4
area=pi4^2=16pi, pi=3.14 so then
50.24
toal is rectangle+circles=144+50.24=194.24 suare feet
rounded
194 square feet
