What is the area of the figure below a. 7.5 b. 15 c. 21.25 d. 42.5

Check the picture below.

let's recall that in a Kite, the diagonals meet at 90° angles, therefore, we know the height of each of those 4 triangles, is 2.5 and 6, now, since the pair of triangles above are 45-45-90 triangles, we can use the 45-45-90 rule, as you see there, so, if the height is 2.5, then the base is also 2.5.

so, we really have 2 pair of triangles whose base is 2.5 and height of 2.5, and another pair of triangles whose base is 2.5 and height is 6, let's add their areas.

The correct answer is option C.  21.25

Step-by-step explanation:

Formula:-

Area of triangle  = bh/2

Where b - Base of triangle and h - Height of triangle

From the figure we can see a two isosceles triangle.

One triangle with base 5 m(2.5 + 2.5) and height 2.5 m

The second triangle with base 5 m and height 6

To find the area of first triangle

Here b = 5 m and h = 2.5 m

Area = bh/2 =(5 * 2.5)/2 = 6.25 m²

To find the area of second triangle

Here b = 5 m and h = 6 m

Area = bh/2 =(5 * 6)/2 = 15 m²

To find total area

Total area = Area of 1st triangle + area of 2nd triangle

  = 6.25 + 15 = 21.25 m²

The correct answer is option C.  21.25

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
