Tom qab ntawd, cia li muab lawv ua ke kom tau qhov cheeb tsam . Hauv lwm lo lus: Thaj chaw = puag × qhov siab, los yog A = b × h rau luv.
Tus qauv rau thaj tsam ntawm txhua daim duab yog dab tsi?
Thaj tsam ntawm cov qauv dav hlau
| Luas = ½ × b × h b = puag h = ntsug qhov siab | luas = a2 a = length of side |
|---|---|
| Rectangle Area = w × h w = dav h = qhov siab | Parallelogram Area = b × h b = puag h = ntsug qhov siab |
