A rectangular plastic sheet measures 65cm by 40cm. Find out the cost price at the rate of rs. 20 per sq.m.

Answer 1

Given Data of Rectangular sheet -

Length = 65 cm

Breadth = 40 cm

Area of rectangular sheet

= Length × Breadth

= ( 65 × 40 ) cm²

= 2600 cm²

= ( 2600 / 10,000 ) m²

= 0.2600 m²

= 0.26 m²

∴ Cost Price of the rectangular sheet at ₹20/m²

= ₹ ( 20 × 0.2600 )

= ₹ 5.2

Hence, the cost price of the rectangular plastic sheet is ₹ 5.2
