Question

A rectangular piece of plastic sheet measures 1m by 70cm find its cost at the rate of rs 80 per square meter

Answer 1

Cost will be 560000 Rupees

Answer 2

Answer:

Rs.56

Step-by-step explanation:

Length of rectangular sheet = 1m

Breadth of rectangular sheet = 70 cm

100 cm = 1 m

So, 1 cm = 0.01 m

70 cm = 70*0.01= 0.7 m

Thus breadth of rectangular sheet = 0.7 m

Area of rectangular sheet = Length * Breadth

                                           = 1 *0.7

                                           = 0.7 sq. m.

Cost of 1 sq,. m. sheet = Rs.80

Cost of 0.7 sq.m. sheet = 80*0.7 = Rs.56

Hence the total cost of rectangular sheet is Rs.56
