Comparing Areas

When comparing different units of area, it's important to convert them to a common unit for accurate comparison. Let's convert the given areas to a common unit and compare them.

- 650m2 is 650 square meters. - 7a 162cm2 can be converted to square meters. 1 are (a) is equal to 100 square meters, and 1 square meter is equal to 10,000 square centimeters. - 30Dm2 24m2 can be converted to square meters. 1 decameter (Dm) is equal to 100 square meters. - 40dm2 3ga can also be converted to square meters. 1 decameter (Dm) is equal to 100 square meters, and 1 hectare (ga) is equal to 10,000 square meters.

Let's convert the given areas to square meters for easier comparison.

Conversion to Square Meters

- 7a 162cm2 = (7 * 100) + (162 / 10000) = 700 + 0.0162 = 700.0162 square meters. - 30Dm2 24m2 = (30 * 100) + 24 = 3024 square meters. - 40dm2 3ga = (40 * 1) + (3 * 10000) = 40 + 30000 = 30040 square meters.

Now, let's compare the areas.

Comparison

- 650m2 is 650 square meters. - 700.0162m2 is 700.0162 square meters. - 3024m2 is 3024 square meters. - 30040m2 is 30040 square meters.

Based on the conversion, 30040m2 is the largest area, followed by 3024m2, 700.0162m2, and 650m2.

Therefore, 30040m2 is the largest, and 650m2 is the smallest among the given areas.
