Question

If the area under a histogram is 40 cm (2) then the area under athe corresponding frequency polygon is what?

Answer 1

The area under the corresponding frequency polygon is 40 cm².

Step-by-step explanation:

• Given data

        Area of histogram = 40 cm²

• Area of frequency polygon is equal to area of histogram.

• This can be understand by drawing of histogram and frequency polygon for any problem.

• First calculate the area of histogram.

• Now calculate the area of frequency polygon. Here we see that at time of calculating the area of frequency polygon ,some part of histogram is left out and same amount is added in somewhere in frequency polygon.

• So this is reason of area of frequency polygon is equal to area of histogram.

• Area of frequency polygon = Area of histogram

• Area of frequency polygon = 40 cm².
