Answer 1

I can help you with your math problems.

The answer to the first problem is:

80 dm = 800 cm 119 cm = 11.9 dm 37 m 4 dm = 3740 cm 374 cm = 3.74 m 2 m = 2000 cm^2 18 dm = 1800 cm = 18000 cm^2

The answer to the second problem is:

The area of a rectangular flower bed is 4 m^2. The length of the flower bed is 2 m 50 cm. Find the width and the perimeter of the flower bed.

To find the width of the flower bed, we need to divide the area by the length:

width = area / length width = 4 m^2 / 2.5 m width = 1.6 m

To find the perimeter of the flower bed, we need to add up the lengths of all four sides:

perimeter = 2 * (length + width) perimeter = 2 * (2.5 m + 1.6 m) perimeter = 2 * 4.1 m perimeter = 8.2 m

I hope this helps. If you need more assistance, please let me know.
