​

Answer 1

Step-by-step explanation:

The Indus Valley Civilization contained more than 1,000 cities and settlements. These cities contained well-organized wastewater drainage systems, ..

Answer 2

Step-by-step explanation:

Answer

Given, Total length of the wire=44cm

∴ The circumference of the circle=2πr=44cm

⇒2×722×r=44

⇒r=2×2244×7=7cm

Now, Area of the circle=πr2=722×7×7=154cm2

Now the wire is converted into square,

Then perimeter of square=44cm

⇒4× side=44

⇒ side=444=11cm

Now, area of square=side×side=11×11=121cm2

Therefore, on comparing the area of circle is greater than that of square, so the circle enclosed more area.
