We have been given 4 points 
. We are asked yo plot these points on coordinate plane and find the area of the figure.
Upon plotting our given points, we will get a rectangle as shown in the attached file.
We can see that the width is 5 units that is difference between y-coordinates of point 
.
We can see that the length of rectangle is 6 units that is difference between x-coordinates of point 
.
We know that area of rectangle is length times width.
Therefore, the area of the figure would be 30 square units.
An example of a part to a whole ratio is the number of females in a class to the number of students in the class. If there are 8 females in the class of 20 students the ratio of girls to students can be expressed 8:20 (females to students). Because this ratio is relating a part to a whole it can also be expressed as a fraction (8/20) or as a percentage (40%).
Answer:
The simple way to calculate a trade-weighted average tariff rate is to divide the total tariff revenue by the total value of imports. Since these data are regularly reported by many countries, this is a common way to report average tariffs.
Let width be W
Then length = 5W
P=2L+2W
P< 96cm
Then the Perimeter of the rectangle is equal to
(2L+2W)< 96
2*(5W)+2W)≤96
Therefore, 2w+2⋅(5w)≤96
should be your answer
