Answer 1

If he makes 16 circular designs each for radius 7 cm on a piece of cloth of dimensions 56cm×56cm and per m²charge is Rs. 150 but he charges Rs. 50 from the customer then he had not asked for correct payment.

Step-by-step explanation:

Dimensions of the piece of cloth = 56 cm x 56 cm

The radius of each embroidery designs, r = 7 cm

No. of circular embroidery designs made by the embroider = 16

∴ Area of 16 circular designs on the cloth = 16 * πr² = 16 * $\frac{22}{7}$ * 7 * 7 = 2464 cm² = 0.2464 m²

The cost of doing embroidery on the cloth is given as Rs. 150 per sq. meter

∴ The total cost of doing 16 embroidery designs on the piece of cloth should be,

= 0.2464 m² * Rs. 150

= Rs. 36.96

We can see that the embroider should charge Rs. 36.96 from the customer for doing a total of 16 designs on the piece of cloth but he charges Rs. 50 from the customer that means he had not asked for the correct payment.
