Length = 20 inches
Width = 16 inches
Missing = 8 inches
There are two shapes in the figure. A rectangle and a square.
We need to get the area of the rectangle and the area of the square. Then, subtract the area of the square from the area of the rectangle to get the total area of the figure.
Area of the rectangle = length x width
= 20 in x 16 in
Area of the rectangle = 320 in²
Area of the square = s² = 8² = 64 in²
Area of the figure = 320 in² - 64 in² = 256 in²

A mapping is said to be function if each element in the domain is related with only one element in the range.Or you can say that a relation is a function also when two different elements in domain have same image or related with same element of the Co domain.
The elements which is related with elements of domain is called Co domain.
So , using the definition of function that i have written above you can classify that the relation is a function or not
1. {(2, 2),(4, 4),(6, 6),(8, 8)}
→→Each element is related with itself , no two different images have different Preimage, For example (2,3),(2,4) that is not happening in this case. so this relation is a function.This kind of function is called identity function.
2. (0, 3),(3, 5),(5, 6),(8, 4)→Different element have different images .So this Relation is a function.
3. (1, 2),(3, 3),(4, 8),(6, 3) →→→Here two elements have same image 3. But still this is a function because two elements in domain or preimage can have same image in a function.
4. (3, 4),(5, 2),(5, 6),(7, 3)→→→This is not a function because two different elements of image have same preimage that is image of 2,and 6 have same preimage which is 5. So this is not a function.
From The given options 1,2,3 are functions.
{(0, 3),(3, 5),(5, 6),(8, 4)} Is a function.
{(1, 2),(3, 3),(4, 8),(6, 3)} Is a function.
{(3, 4),(5, 2),(5, 6),(7, 3)} Is not a function.
For a relation to be a function, every x value must have only one y value.
Hope this helps.

7 as a percentage of 20 just means what percentage of 20 is 7. To do this, we must divide 7 by 20. This is how you answer this. If you do so, then you will get 0.35. This shows that it is 35%. Note that when you get a decimal number, then you must multiply it by 100% to get the percentage equivalent of that number. Therefore, 7 as a percentage of 20 is 35%.
7 ÷ 20 = 0.35
And then, all we need to do is convert the resulting decimal into a percentage. We can do this by either multiplying the result by 100, or (my personal shortcut) just shifting the decimal point over two places to the left.
0.35 = 35%
Which is our answer.
7 is 35% of 20.
Hope that helped! =)
