Explanation / Answer

1) option (c) The area of the rectangle is 125.67 is correct option.

Exp..

printf("The area of the rectangle is %6.2f",area);

Between % and f, we write 6.2, that is, the field width, followed by a . (point), followed by the number of decimal places. The value is rounded to the stated number of decimal places and then printed. Here, the value printed will be 125.67, which occupies exactly 6 print columns. If the field width were bigger, the number will be padded on the left with spaces. If the field width were smaller, it is ignored, and the number printed using as many columns as necessary.

2) option (c) z=(double)a/(double)b; is correct option.

Exp:

z=(double)a/(double)b; for divison we need to typecast the Numerators and denominators in double.
