A 12 m by 8 m rectangular floor has a 4 m by 3 m rectangular closet cut out from one corner.
What is the area of the remaining floor?
Correct Answer
84 cm2
Explanation
Whole rectangle: \( 12 × 8 = 96 \text{ } m^2 \). Closet: \( 4 × 3 = 12 \text{ } m^2 \). Remaining area \( = 96 − 12 = 84 \text{ }m^2 \).
