NCERT Solutions for Chapter: Area and its Boundary, Exercise 6: King's Story

The King was very happy with carpenters Cheggu and Anar. They had made a very big and beautiful bed for him. So as gifts the king wanted to give some land to Cheggu, and some gold to Anar. King’s Story Cheggu was happy. He took $100 \mathrm{m}$ of wire and tried to make different rectangles. He made a $10 \mathrm{m}\times 40 \mathrm{m}$ rectangle. Its area was $400 \mathrm{sq}. \mathrm{m}$. So he next made a $30 \mathrm{m}\times 20 \mathrm{m}$ rectangle.

What is its area? Is it more than the first rectangle?

Anar tried many ways to make a boundary for $800 \mathrm{sq}. \mathrm{m}$ of land. He made rectangles A, B and C of different sizes. How much gold wire will he get for these rectangles?

The length of gold wire for A $=$_____ $\mathrm{m}$.

Anar tried many ways to make a boundary for $800 \mathrm{sq}. \mathrm{m}$, of land. He made rectangles A, B and C of different sizes. How much gold wire will he get for these rectangles?

The length of the gold wire for B $=$_____ $\mathrm{m}$.
