Answer:
55 units^2
Explanation:
Ooo, this is a fun one!
So, firstly, let's find the area of the rectangle. The area of a rectangle is length*width. We can see that the length is 9, and the width is 5. So the area of the rectangle is 45 units^2.
The area of a triangle is (length*width)/2
To find the length and width of the triangle, we need to subtract 9 from 13 (this will find the side to the right of the triangle) and the top side of the triangle will be 5, as we can see from the top side of the rectangle. Since 13 - 9 = 4, we can see that width = 5 and length = 4.
(4*5)/2 = 10
So the area of the triangle is 10 units^2
Adding the two areas together, we get 55 units^2
Hope this helped!
