Question

is it possible to design a rectangular mango grove whose length is twice it's breadth and the area is 800m . if so, find length and breadth

Answer 1

Let the length and breadth be 'l' and 'b' respectively.
A/c to qst, l = 2b
We know, l × b = 800
[ As, Area = Length × Breadth]
2b × b = 800
2b^2 = 800
b^2 = (800/2) = 400
b = 20
Hope it'll help u...

Answer 2

Let breadth be considered x then length is 2x Area =length * breadth
800= 2x*x
800=2xsquare
800/2 = xsquare
400=xsquare
$\sqrt{400} equals x$
20=x=breadth
Length =2x=2*20=40
