tanda sifar = zero mark Place one end of the object exactly on the 0 mark of the ruler. Starting from 0 means the number at the other end is already the length. Many rulers have a small blank space before 0, so look for the printed line, not the edge. Example: an eraser starts at 0 and ends at 6, so it is 6 - 0 = 6 cm long. Watch out: the very edge of a ruler is often not the zero line.
Langkah 2
Baca hujung yang satu lagi
Lihat nombor pada hujung objek yang satu lagi dan rekod bersama unit.
hujung yang satu lagi = 另一端 东西对好起点后，看另一端对着哪一个数，把这个数和单位一起记下来，例如 12 cm。眼睛要从正上方看，才不会读歪。 例子：一支笔量到 14，另一支量到 11，两支相差 14 - 11 = 3 cm。 注意：另一端落在两条刻度线中间时，要选比较接近的那一条。
hujung yang satu lagi = the other end After lining up the start, look at the number beside the other end and record it with the unit, like 12 cm. Look from straight above so the reading is not tilted. Example: one pen reaches 14 and another reaches 11, so they differ by 14 - 11 = 3 cm. Watch out: if the end falls between two lines, choose the line that is closer.
Langkah 3
Lukis garis lurus
Tandakan titik mula dan titik akhir, kemudian sambungkan dengan pembaris. Garis 1 m bermula pada 0 dan berakhir pada 100 cm, kerana 1 m = 100 cm.
garis lurus = straight line Mark a start point and an end point first, then join them using a ruler. Hold the ruler firmly and slide the pencil along its edge in one stroke. For a line of a set length, put the start point at 0. Example: to draw a 7 cm line, dot at 0 and at 7; the length is 7 - 0 = 7 cm. Watch out: press the middle of the ruler so it does not slide while you draw.

tanda pada pembaris = mark on the ruler The question asks which ruler mark the end of an object should sit on. Recall the method from Langkah 1 and think about where to start so that the reading equals the length directly. Try it with a ruler. Example: measuring from 2 to 10 means working out 10 - 2 = 8 cm, an extra step. Watch out: this is about the starting position, not the end.

Objek bermula pada 0 dan berakhir pada 9 cm. Panjangnya…
panjang objek = length of the object The object starts at 0 and stops at a certain mark, and the question asks for its length. The clue is that the start is exactly at 0, so only the end position matters. Check by doing end minus start. Example: a matchstick from 0 to 4 cm is 4 - 0 = 4 cm long. Watch out: do not read the next number after the end; being off by one gives a wrong length.
Ringkasan
Syabas!
