A square paper is cut into 16 smaller equal square pieces. If the perimeter of each small piece is 24 cm, find the area of the original paper.
Show answer & explanation
Correct answer: B
Explanation
Perimeter of a small square = 24 cm; Total number of small squares = 16
Perimeter of a square = 4a
Area = a²
4a = 24
a = 6 cm
Area of a small square = 6² = 36
Total area = 16 × 36 = 576 cm²
