Question

sheetal wants to put lace around the table cloth whose dimensions are 32 16 metre find the length of lens required also find the cost of if it is cost rupees 5 per metre​

Answer 1

Answer:

circumference =πd=1.5πm

length of lace required = circumference of circle

=1.5×3.14=4.71m

length of lace required =4.71m

one meter of lace =Rs.15

4.71m lace =?

=  

1

4.71×15

​

=Rs.70.65

It costs 70.65Rs. to buy 4.71m of lace

Step-by-step explanation:

Answer 2

Given:

1. Length of table cloth = 32m
2. Breadth of table cloth = 16m
3. Cost of cloth per meter = Rs 5

To find:

1. Length of lace required
2. Cost of lace required

Solution:

1. To put lace around the table cloth, we need to calculate its perimeter.
2. The formula for the perimeter of a rectangle is as follows

                                   2(l + b) = perimeter

Where,

l= length of table cloth

b= breadth of table cloth

Perimeter of the table cloth will be = 2(32+16) = 96m

We know, cost per meter of lace = Rs 5

Amount of lace required = 96m

Cost of total lace = Rs 5 x 96m = Rs 480

Thus, the total length of lace required to put around the table cloth is 96m and its total cost will be Rs 480.
