find the area. 13mm 15mm 26mm 32mm ( PLEASE EXPLAIN or I give 2 stars)

Answer:
[tex]A_{total} = 623\ mm^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the bottom rectangle
[tex]A = l * w[/tex]
[tex]A = 32\ mm * 15\ mm[/tex]
[tex]A = 480\ mm^2[/tex]
Step 2: Determine the area of the top rectangle
[tex]A = l * w[/tex]
[tex]A = 13\ mm * (26\ mm - 15\ mm)[/tex]
[tex]A = 13\ mm * 11\ mm[/tex]
[tex]A = 143\ mm^2[/tex]
Step 3: Determine the total area
[tex]A_{total} =480\ mm^2 + 143\ mm^2[/tex]
[tex]A_{total} = 623\ mm^2[/tex]
Answer: [tex]A_{total} = 623\ mm^2[/tex]
