उत्तर
Step 1: Dimensions of each napkin
- The original square cloth has a side length of 1 m.
- Since the cloth is divided into 4 equal smaller squares, each napkin will have a side length:
Side length of each napkin = `(1 m)/2 = 0.5 m`
Step 2: Perimeter of one napkin
The perimeter of a square is given by:
P = 4 × Side length
For one napkin:
P = 4 × 0.5 = 2m
Step 3: Total lace required
Since there are 4 napkins, the total lace required is:
Total lace = 4 × 2 = 8m
The total length of lace required to trim all four sides of all the napkins is 8 meters.
