Ram painted a 6m 50cm long strip on the road on Monday and 9m 90cm long strip on Tuesday. What is the length of the road he covered?

Options

A. 16m 140cm
B. 16m 40cm
C. 13m 130cm
D. 13m 40cm

Answer

To find the total length of the road Ram covered by painting strips on Monday and Tuesday, we will follow these steps:

### Step 1: Convert the lengths into the same unit
We need to convert the lengths from meters and centimeters into centimeters for easier addition.

- **Monday's strip:** 6 meters 50 centimeters
- Convert 6 meters to centimeters:
\[ 6 \text{ m} = 6 \times 100 \text{ cm} = 600 \text{ cm} \]
- Therefore, Monday's strip in centimeters is:
\[ 600 \text{ cm} + 50 \text{ cm} = 650 \text{ cm} \]

- **Tuesday's strip:** 9 meters 90 centimeters
- Convert 9 meters to centimeters:
\[ 9 \text{ m} = 9 \times 100 \text{ cm} = 900 \text{ cm} \]
- Therefore, Tuesday's strip in centimeters is:
\[ 900 \text{ cm} + 90 \text{ cm} = 990 \text{ cm} \]

### Step 2: Add the lengths together
Now that both lengths are in centimeters, we can add them:
\[ 650 \text{ cm} + 990 \text{ cm} = 1640 \text{ cm} \]

### Step 3: Convert the total back to meters and centimeters
To convert 1640 centimeters back into meters and centimeters:
- Divide by 100 to find the meters:
\[ 1640 \text{ cm} = 16 \text{ m} \text{ and } 40 \text{ cm} \]

### Final Answer
The total length of the road Ram covered is **16 meters 40 centimeters**.
