Question 9637
If 1 inch = 2.54cm

11inches = 11x2.54 =  27.94cms

Here's a trick for multiplying with 11.Starting from the right side,write down the right most digit in this case 4. Then,add the rightmost digit and the digit to the left of it 4+5 = 9(If its greater than 9,write the left digit and carry forward).Now we add 2+5 = 7.And finally we write the left most digit as it is in this case 2. Since there are two digits after the decimal place,we place the decimal point 2 places from the right.
