Area of the given figure is in²

Step-by-step explanation:

Firstly, finding the area of triangle by substituting the values in the formula

Hence, the area of triangle is 18 in².

Secondly, finding the area of rectangle by substituting the values in the formula :

Hence, the area of rectangle is 66 in².

Now, finding the total area of given polygon by substituting the values in the formula :

Hence, the area of given figure is 84 in².

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

m∠a is 90°

m∠b is 40°
