Answer:

The formula for area of a parallelogram is either $A=bh$ or $A=\dfrac{d_1d_2}{2}$ .

Step-by-step explanation:

If base and vertical height of a parallelogram are given, then the area of the parallelogram is:

$A=bh$

Where, <em>b</em> is base and <em>h</em> is the vertical height of the parallelogram.

If measures of both diagonals are given, then the area of the parallelogram is:

$A=\dfrac{d_1d_2}{2}$

Where, $d_1,d_2$ are the two diagonals of the parallelogram.

Ilya [14]

Answer:

Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:

For 2006 we have:

103+297+210+213+137 = 960 total sales

For 2007 we have:

127+223+210+285+259 = 1104 total sales

The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:

For the total number of coats we have that the percent increase is: $\frac{1104-960}{960} * 100= 15$ %

For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: $\frac{127-103}{103} * 100= 23.3$ %

Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:

23.3 % - 15% = 8.3%
