Question

Nasreena is a farmer who wants to divide her land equally among her three children — Chumki, Jhumri and Imran. She wants to divide the land so that each piece of land has one tree. Her land looks like this.



• Can you divide the land equally? Show how you will divide it. Remember each person has to get a tree. Colour each person's piece of land differently.
• If each square on this page is equal to 1 square metre of land, how much land will each of her children get? ___________ square m
Chumki, Jhumri and Imran need wire to make a fence.
• Who will need the longest wire for fencing? __________
• How much wire in all will the three need? ___________

Answer 1

There are 10 squares along the length, and 9 squares along the width.
So, the total number of squares on the land = 10 $\times$ 9
= 90
Now, area of each square = 1 square m
So, area of complete land = area of 90 squares
= 90 $\times$ 1 square m
= 90 square m

Nasreena has 3 children namely Chumki, Jhumri and Imran, and she divides her land equally among her children.
So, area of land each child gets = $\frac{90}{3}$ square m
= 30 square m


• Both Chumki and Jhumri will need 28 m of wire for fencing.
• Imran will need 26 m of wire for fencing his part of the field.

Thus, total wire required by all three of them = 28 + 28 + 26
= 82 m
