130 i think let me know if this is right
The area of a trapezoid if found using the formula
A = (base1 + base2)/2 x height
Area = (3+5)/2 x 1.5
Area = 8/2 x 1.5
Area = 4 x 1.5
Area = 6 square feet.
It the fourt day the total is 0.70 because
Day one: .10
Day two: you double it so .20
Day three: you double it again so .40
Day four: you add .30 so .70 is the total
