Answer 2

Answer:

Required length of lace=360cm or 3.6m

cost of total lace= 36Rs.

Step-by-step explanation:

GIVEN THAT SIDE OF TABLE CLOTH IS 90cm AND TABLE CLOTH IS OF SQUARE SHAPED

SO REQUIRED LENGTH OF LACE = PERIMETER OF TABLE CLOTH

Perimeter of table cloth= 4a [ a = side of square ]

=4(90)

=360cm

Now, cost of 1m lace = 10Rs.

" 100cm lace= 10Rs.

" " 1cm lace= 10/100

=0.1 Rs.

cost of 360cm lace= 0.1*360

= 36Rs.
