To solve the given calculations:

a) 1,15 hectares + 250 ares - 1800 square meters = ... hectares

1 hectare = 100 ares = 10,000 square meters

1 are = 100 square meters

Convert 1.15 hectares to square meters:

1.15 hectares = 1.15 * 10,000 = 11,500 square meters

Now, convert 250 ares to square meters:

250 ares = 250 * 100 = 25,000 square meters

Subtract 1800 square meters:

11,500 + 25,000 - 1800 = 35,700 square meters

b) 4124 square centimeters + 0.22 square meters - 3500 square millimeters = ... square decimeters

1 square meter = 10,000 square centimeters

1 square meter = 100 square decimeters

Convert 0.22 square meters to square centimeters:

0.22 square meters = 0.22 * 10,000 = 2,200 square centimeters

Now, convert 4124 square centimeters to square decimeters:

4124 square centimeters = 4124 / 100 = 41.24 square decimeters

Convert 3500 square millimeters to square centimeters:

3500 square millimeters = 3500 / 100 = 35 square centimeters

Add and subtract:

41.24 + 2,200 - 35 = 2,206.24 square decimeters

c) 14 cubic decimeters + 2300 cubic centimeters + 0.03 cubic meters = ... cubic decimeters

1 cubic meter = 1,000,000 cubic centimeters

1 cubic meter = 1,000 cubic decimeters

Convert 0.03 cubic meters to cubic decimeters:

0.03 cubic meters = 0.03 * 1,000 = 30 cubic decimeters

Add 14 cubic decimeters and 2300 cubic centimeters:

14 + 2300 / 1000 = 16.3 cubic decimeters

Add all:

16.3 + 30 = 46.3 cubic decimeters

d) 0.0000725 cubic decameters + 0.0426 cubic meters + 1175,000 cubic millimeters = ... cubic centimeters

1 cubic meter = 1,000,000 cubic centimeters

1 cubic meter = 100 cubic dec
