Tomorrow is Sita's birthday and I need to make paper bags to give her gifts .
What happened Tia? Why are you crying ?
Mom for making a paper bag, a rectangle 15cm × 10cm is required. So , I have to find the cost of 5 paper bags if cost of paper is ₹2 per cm square
Ok , Good but how can I help you because crying is not a solution to problems .
Yes ,mom but I don't know how to solve it .
It's easy
Ok , Thank You mom
ok , I will help you to solve this question .
So , first you need to find the Area of the rectangle , that is = l×b =(15×10) =150 cm sqSo , the Cost of a paper= ₹2 per cm sqCost of making a paper bag= 2×150=₹ 300Cost of making 5 paper bags= 5×300= ₹1500Hence you will be needing ₹ 1500 for making paper bags
Mom , that's easy thank you so much for explaning me the problem
