Question

A rectangular field is 0.3 kilometers long and 0.15 kilometers wide. What is the area of the field in square meters?

Answer 1

To find the area of the rectangular field in square meters, convert the dimensions from kilometers to meters and then multiply them together, resulting in 45,000 square meters.

Step-by-step explanation:

To calculate the area of a rectangular field that is 0.3 kilometers long and 0.15 kilometers wide, use the following steps:

1. Convert the dimensions from kilometers to meters. Since there are 1,000 meters in a kilometer, the length in meters is 0.3 km × 1,000 = 300 meters and the width is 0.15 km × 1,000 = 150 meters.
2. Multiply the length and width in meters to get the field's area in square meters. So the area is 300 m × 150 m = 45,000 square meters.

Answer 2

4.5 meters

Step-by-step explanation:

The formula for the area of a rectangle is length x width. Using this formula, you can substitute the given information and find the area:

length x width = area

0.3km x 0.15km = area

0.045km = area

Finally, you can now convert square kilometres into square meters by multiplying by 100:

0.045 x 100 = 4.5 meters
