A rectangular piece of plastic sheet measures 65 cm by 40 cm. Find its cost at the rate
of 20 per sq. m.​

Answer 1

Answer:

5.20RS

Step-by-step explanation:

dimensions of plastic sheet = 65×40 cm

area of plastic sheet = L×B=65×40=2600cm sq

1 m sq = 10000 cm sq

so 2600 cm = 0.26 m sq

cost of 1 m sq = 20 rs

cost of 0.26 m sq = 0.26×20= 5.20 rs
