Kalkulator Trapesium
Hitung luas, tinggi, atau salah satu alas trapesium dari tiga nilai lainnya. Tampilkan panjang median (midsegmen), dan — dengan panjang kaki — perimeter serta klasifikasi trapesium sama kaki/scalene, plus diagram berlabel.
Input
Kosongkan SATU dari alas a, alas b, tinggi, atau luas — sisanya akan dihitung dari tiga lainnya.
Output
Diagram trapesium akan muncul di sini setelah perhitungan selesai.

Panduan
Solve a trapezoid's area, height, or either parallel base from the other three values, plus its median (midsegment) length. Add the two leg (non-parallel side) lengths for the perimeter and an isosceles/scalene classification, and get a labeled diagram either way.
The formula
For a trapezoid with parallel bases a and b and height h (the perpendicular distance between them):
area = (a + b) / 2 × hThe median (or midsegment) — the segment connecting the midpoints of the two legs — always has length (a + b) / 2, which is also area / h.
Solve for any of the four
Leave any ONE of base a, base b, height, or area blank and the calculator solves for it from the other three:
- Missing area →
area = (a + b) / 2 × h - Missing height →
h = 2 × area / (a + b) - Missing base a →
a = 2 × area / h − b - Missing base b →
b = 2 × area / h − a
If all four are supplied, the calculator checks they're consistent and flags it if they aren't.
Perimeter and shape (optional)
Fill in leg 1 and leg 2 (the two non-parallel sides) and the calculator also reports:
- Perimeter —
a + b + leg 1 + leg 2 - Shape — isosceles (equal legs) or scalene
How to use it
- Enter any three of base a, base b, height, and area — the fourth is solved for you.
- Optionally add both leg lengths for the perimeter and shape classification.
- Read the labeled diagram and the full solution, or copy the SVG source.
All calculations run in your browser — nothing is uploaded.
What if my four values don't match up?
If you fill in all four of base a, base b, height, and area, the calculator verifies area = (a + b) / 2 × h and tells you what area those three dimensions actually give if it doesn't — leave one field blank instead to have it solved for you.
