Question

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 1

Answer:l=40,b=20;

Area=lb

=(2b)b

800=2b²

b²=400

b=20

l=2b=40

Step-by-step explanation:

Answer 2

Answer:

yes

Step-by-step explanation:

l=2b where l is length, b is breadth

Area of rectangle= l×b

the eqn is:

l×b=800

2b×b=800

2b^2=800

b^2=400

b=20

use the concept of discriminant to prove.

b^2 -4 ac should be equal to or greater than 0
