    Histogram help please!

    I am stuck on this question.. I need to draw a histogram but don't know how! I need urgent help please.. Here is the table:

    Area (A cm²) Frequency

    0 < A ? 10 38
    10 < A ? 25 36
    25 < A ? 40 30
    40 < A ? 60 46

    I don't know how to draw the histogram because on this small grid i am given (on this past paper), it isn't big enough to have each square represent 2, which i think is the highest common factor..

    Can anyone help? With a rough histogram..?

    Thanks

    Hello, Danielisew!

    I need to draw a histogram.

    \begin{array}{cc}\text{Area (cm}^2) & \text{Frequency}\\<br />
0 < A < 10 & 38 \\<br />
10 < A < 25 & 36 \\<br />
25 < A < 40 & 30 \\<br />
40 < A < 60 &  46\end{array}

    You could cut a "slice" out of the histogram.
    Code:
            |
         46 +                    *------*
            |                    |      |
            |                    |      |
         38 *------*             |      |
            |      |             |      |
         36 +      *------*      |      |
            |      |      |      |      |
            |      |      |      |      |
         30 +      |      *------*      |
            |      |      |      |      |
        ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~`~ ~ ~ ~ ~
        ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
            |      |      |      |      |
          0 +------+------+------+------+
            0     10     25     40     60

    This is common practice when all the data is,
    . . for example, between 100 and 110.
