<u>Step 1: Determine the area of the top rectangle</u>
We can tell that the total shape seems like two rectangles glued together. We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them. Lets first solve the left rectangle.



<u>Step 2: Determine the area of the bottom rectangle</u>



<u>Step 3: Determine the total area</u>

Step by step explanation :
Answer:
AD = 5 units
Step-by-step explanation:
Given:
Perimeter = 18 units
BC = 4 units
CD = 3 units
Required:
Length of segment AD
Solution:
Perimeter = AB + BC + CD + AD
We can easily find AB,
AB = 6 units (distance from A to B)
Plug in the values
18 = 6 + 4 + 3 + AD
18 = 13 + AD
Subtract 13 from each side
18 - 13 = 13 + AD - 13
5 = AD
AD = 5 units
