Question

A table cover 4m× 2m is spread on a table Find the cost of polishing the top of the table at rupees 2.25 per sq m if 25 cm table cover is hanging all round the table​

Answer 1

Step-by-step explanation:

25 cm = 0.25 m

Length of the table top = 4m - (2 × 0.25)m = 4m - 0.50m = 3. 5 m

Bredth of the table top = 2m - (2 × 0.25)m = 2m - 0.50m = 1. 5 m

Area of the table top = l × b = 3. 5 × 1. 5 = 5.25 m2

Cost of polishing the table top at ₹25 per square metre = 5. 25 × 25 = Rs. 131.25
