Question

Q.4. As shown in the figure, 6 napkins all of the
same size were made from a rectangle piece of
cloth length 3 m and
breadth 2 m. What
length of lace will be
required to trim all
four sides of all the
napkins?​

Answer 1

Answer:

perimeter of a rectangle = 2(l+b)

length = 3m

breadth = 2m

perimeter = 2(3+2) = 10m

no. of napkins = 6

so, amount of lace required = 6×10

= 60m

thus, 60m lace will be required
