Question

Is it possible to design a rectangular mango grove whose length is twice its breadth, and the area is $800m^2$? If so, find its length and breadth.

Answer 1

Rectangular mango grove,

whose length l & twice its breadth,

Let the breadth$=$x

length$=2x$

so,

Area of rectangle$=200m^2$

Length & Breadth$=800$

$2x\times x=800$

$2x^2=800$

$x^2=400$

$x^2=(20{)}^2$

$x=20$cm

then, length$=2x=2\times 20$

$=40$cm

Length$=40$cm

Breadth$=20$cm.
