Answer:
48 cm
Step-by-step explanation:
Here, we are concerned with finding the perimeter of the rectangle.
Now, since the square has an area of 9 cm^2, it means that the squares has a side of 3 cm each since the area of a square is s^2
So now, there are 5 squares in a row, meaning in a straight stretch , left to right or right to left, there are 15 squares. So the total length here is 5 * 3 = 15 cm
Now, moving column-wise, from top to bottom, since we have 3 rows, what this means is that per column of the rows, there are 3 squares. So the total length here becomes 3 * 3 = 9 cm
So we have a rectangle 9cm by 15cm
The perimeter is thus 2(L + B) = 2(15 + 9) = 2(24) = 48 cm
