Question 132
Solve the following question:
The area of a square plot is 1011400 m2. Find the length of one side of the plot.
Let the length of the square plot be a. Then, the area of square =a2
According to the question,
Area =1011400m2 [given]
∴a2=1011400⇒a2=40401400⇒a=√40401400⇒a=√201×20120×20
∴a=20120=10120m [taking square root on both sides]
Hence, the length of one side of the plot is 10120m.
