Question

a wooden sheet is 15m long and 6m broad. It has to be painted on both the sides. Find the cost of painting at rupees 50 per square metre. ​

Answer 1

Answer:

area =15*6=90sq.m.

painted on both sides so area*2=90*2=180sq.m.

cost of 1 SQ.m. =50/-

cost of painting 180 SQ.m.=50*180=RS.9,000/-

Answer 2

Area of sheet= 15×6= 90m²

Area of both sides= 90×2=180m²

Cost of painting= RS.50/m²

Cost of painting 180m²= 180×50= 9000

Therefore cost of painting 180m² is

RS.9000
