Question

Now tell me the solution of this question kavana wants to put a lace border all around a rectangular board cover ,4cm long and 3m wide .Find the length of the lace required by Kavana.

Answer 1

Answer:

perimeter of a rectangle= 2*(length+breadth)

therefore, the perimeter of the rectangular board cover= 2*(4cm+ 3m)

and as 1m= 100cm, 3m= 300cm

therefore, the length of lace required by Kavana= 2*(4+300)

= 2*304

= 608 cm
