The length is 5 m and breadth is 0.5m height is 20cm calculate it's area and volume?

To calculate the area of the object, we use the formula:

Area = Length x Breadth

Area = 5m x 0.5m
Area = 2.5 square meters

To calculate the volume of the object, we use the formula:

Volume = Length x Breadth x Height

First, we need to convert the height from centimeters to meters:

Height = 20cm = 0.2m

Volume = 5m x 0.5m x 0.2m
Volume = 0.5 cubic meters

Therefore, the area of the object is 2.5 square meters and the volume is 0.5 cubic meters.

Area:

The area of the rectangular prism is given by:

```
Area = 2(length x breadth + breadth x height + length x height)
```

Substituting the given values:

```
Area = 2(5 m x 0.5 m + 0.5 m x 0.2 m + 5 m x 0.2 m)
Area = 2(2.5 m² + 0.1 m² + 1 m²)
Area = 2(3.6 m²)
Area = 7.2 m²
```

Volume:

The volume of the rectangular prism is given by:

```
Volume = length x breadth x height
```

Substituting the given values:

```
Volume = 5 m x 0.5 m x 0.2 m
Volume = 0.5 m³
Volume = 500 cm³
```
