As shown in the figure, three rectangles of the same size just make a square. The perimeter of the square is 48 cm. Find the perimeter of each rectangle In the following figure, three rectangles are stacked horizontally

As shown in the figure, three rectangles of the same size just make a square. The perimeter of the square is 48 cm. Find the perimeter of each rectangle In the following figure, three rectangles are stacked horizontally

48 △ 4 = 12 (CM) 12 cm is the side length of a square, which is the length of the original rectangle
12 △ 3 = 4 (CM) 4cm is the width of a rectangle, because three rectangles together are equal to a square, that is, three widths are equal to one length
So the circumference of rectangle = (12 + 4) × 2
=16×2
=32 (CM)
