Trapezoid Calculator
Find a trapezoid's area and median from its two bases and height, plus the perimeter if you know the legs.
Area
26
- Median (midsegment)
- 6.5
Show the work
Median: the average of the two bases
m = (a + b) ÷ 2
(8 + 5) ÷ 2 = 6.5
Area = median × height
A = m × h
6.5 × 4 = 26
How it works
Area = (a + b) ÷ 2 × h; median = (a + b) ÷ 2; perimeter = a + b + c + d
Questions
- How does the trapezoid calculator work?
- Area = (a + b) ÷ 2 × h; median = (a + b) ÷ 2; perimeter = a + b + c + d.
