This figure is made up of a rectangle and parallelogram.
what is the area of this figure?
enter your answer in the box. do not round any side lengths

First, let's divide the figure in two parts, called "A" and "B (View the figure attached):

 a: The paralelogram
 b: The rectangle

 To find the area of the parallelogram, we must apply the following formula:

 A=bxh

 b: is the base of the parallelogram.
 h: the height of the parallogram.

 We can know the length of the base and the heigh by the figure shown in the problem:

 b=4
 h=3

Then, we have:

 A(a)=bxh
 A(a)=4x3
 A(a)=12

 Now, we must proceed to find the area of the rectangle, by using the formula:

 A(b)=bxh

 b=9 (the base of the rectangle)
 h=3 (the height of the rectangle)

 A(b)=9x3
 A(b)=27
 
 Then, the area of the figure is:

 At=A(a)+A(b)
 At=12+27
 At=39

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
