Please help. This is finding the area of a rectangle.

Nezavi [6.7K]

Answer:

2500 ft²

Step-by-step explanation:

The missing area at lower right in the diagram has dimensions...

(4-2 1/4) by (3 - 1 3/4) by (1 1/4)

Then 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 the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²

Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²

Then the actual store area is....

9.8125(256 ft²) = 2512 ft²

Rounded to the nearest 50 ft², this is 2500 ft².
