Explanation:

To find the cost of painting the blackboard, we first need to calculate its area.

Length of the blackboard = 5m 20cm = 5.20m

Breadth of the blackboard = 3m 40cm = 3.40m

Area of the blackboard = Length x Breadth

Area = 5.20m x 3.40m

Area = 17.68 square meters

The cost of painting 1 square meter at the rate of Rs. 10 is Rs. 10. Therefore, the cost of painting 17.68 square meters is:

Cost = Area x Rate

Cost = 17.68 square meters x Rs. 10 per square meter

Cost = Rs. 176.80

Therefore, the cost of painting the blackboard at the rate of Rs. 10 per square meter would be Rs. 176.80.
