A trapezoid has an area of 166.5 in.?, a height of 9 in., and one base measuring 15 in. What is the length of (1 point) the other base?
We can use the formula for the area of a trapezoid:
Area = (1/2)*(sum of bases)*(height)
We know the area is 166.5 in^2, the height is 9 in., and one base is 15 in. Let x be the length of the other base. Then we can plug in these values and solve for x:
166.5 = (1/2)*(15 + x)*(9)
333 = (15 + x)*(9)
37 = 15 + x
x = 22
Therefore, the length of the other base is 22 inches.
