Answer:
The area of the smaller rectangular part is 14 in².
Step-by-step explanation:
The smaller rectangular part has dimensions 7 in by 2 in. The area of it is the product of these dimensions:
area = (7 in)×(2 in) = 14 in²
___
Comment on the implied problem
The area of the larger, lower rectangular part will then be the difference between the total area and that of the upper, smaller rectangular part:
large rectangle area = 74 in² -14 in² = 60 in²
That, too, is the product of the length and width of the rectangle, so ...
60 in² = (b)×(5 in)
12 in = b . . . . . . . . . divide by 5 in
