Answer:
10 Square Inches
Step-by-step explanation:
Trapezoid
Base =12 inches
Height =10 inches
Top side= 10 inches.
Area of a Trapezoid[tex]=\frac{1}{2}(a+b)h, $where a and b are the lengths of the base and top respectively$[/tex]
[tex]=\frac{1}{2}(10+12)*10\\=5*22=110 \:Square\:Inches[/tex]
Area of the Trapezoid=110 Square Inches
Rectangle
Base = 12 inches
Height =10 inches.
Area of a Rectangle=Base X Height
=12 X 10
=120 Square Inches
Difference in Area between the two packages
Difference=Area of Rectangle-Area of Trapezoid
=120-110
=10 Square Inches
