(Q10)Is it possible to design a rectangular mango grove whose length is twice its breadth, and the area is 800 m2? If so, find its length and breadth.

Answer

Let the breadth = x m

Then length = 2x m

Area = length × breadth = x.(2x) = 2x2 m2

By problem 2x2 =

x2 =

x = √

x = ±

∴ breadth x = m 1

length 2x = 2 × = m.
