Given:
Area = 150
Height = 14
Base =14
Determine the other base of the trapezoid.
Formula for the area of the trapezoid:
A = (a + b)/2 (h)
b = 2A/h - a
Solution:
Substitute the given values to the formula for the base of the trapezoid in terms of the area.
b = 2 (150)/14 - 14
b = 300/14 - 14
b = 21.43 - 14
b =7.43
Final answer:
b =7.43
