Answer:
[tex]A_{shaded} = 106\ m^2[/tex]
Step-by-step explanation:
Step 1: Get the area of the inside box
[tex]A=l*w[/tex]
[tex]A_{inside\ box} = 7\ m* 2\ m[/tex]
[tex]A_{inside\ box} = 14\ m^2[/tex]
Step 2: Get the area of the outside box
[tex]A = l * w[/tex]
[tex]A_{outside\ box} = 12\ m * 10\ m[/tex]
[tex]A_{outside\ box} = 120\ m^2[/tex]
Step 3: Subtract the inside box from the outside box
[tex]A_{shaded} = A_{outside\ box} - A_{inside\ box}[/tex]
[tex]A_{shaded} = 120\ m^2 - 14\ m^2[/tex]
[tex]A_{shaded} = 106\ m^2[/tex]
Answer: [tex]A_{shaded} = 106\ m^2[/tex]
