If there are 10 squares total: Each square has a perimeter of 4.8. The four sides of a square are all equal. 4.8 = Perimeter 4 = Four (equal) sides of the square 4.8 ÷ 4 = 1.2 1.2 = The length of one side 1.2 × 1.2 = 1.44 1.44 = The area of one square Since there are ten squares, you multiply the area of one square by 10. 1.44 × 10 = 14.4 14.4 units squared = The area of all ten squares (the answer)
