Answer:
Area of a parallelogram would be 13.46
Step-by-step explanation:
Since area of a parallelogram is represented by the formula
Area = (
Where and
are two diagonals of the given parallelograms.
In the given figure and
= BD
We will find the length of and
first
Since points A and C are (3,6) and (5,1)
So distance AC =
=
=
Since B and D are the points (6, 5) and (2, 2)
So length of BD =
BD =
Now we will put these values in the formula
Area of parallelogram =
= ×
= (2.5) (5.385)
= 13.46
The Venn diagram to illustrate this information is given in the image attached.
<h3>What is the Venn diagram about?</h3>The number of children who took plantain and beans only are:
Let beans = a
Rice = b
Plantain = P
So: a + b = 24 - 9 - 5 = 10
Note that 24 children took plantain.
9 children took only Plantain.
5 took the 3 food items.
So:
b + c = 18 -2 - 5 = 11
a + c = 21 - 3 - 5 = 13
P∩B = a + 5
= 6 + 5 = 11
R ∩ B = C + 5
=7 + 5 = 12
None of the three items of food =
50 - (3 + 2 + 9 + 6 + 4 + 7 + 5)
= 50 - 36
=14
