Answer:
2500 ft²
Explanation:
The missing area at lower right in the diagram has dimensions ...
(4 -2 1/4) by (3 -1 3/4) = (1 3/4) by (1 1/4)
Then the area of that "missing" space is ...
(1.75)(1.25) = 2.1875 . . . . square inches.
The area of the enclosing rectangle is ...
(4 in)(3 in) = 12 square inches
Then the area in the diagram representing the store is ...
12 in² -2.1875 in² = 9.8125 in²
__
Each square inch on the diagram represents an actual area of ...
(1 in)×(1 in) ⇒ (16 ft)×(16 ft) = 256 ft²
Then the actual store area is ...
9.8125(256 ft²) = 2512 ft²
Rounded to the nearest 50 ft², this is 2500 ft².
