Question

Is it possible to design a rectangular mango grove whose length is twice its breadth and the area is 800square metres . If so find its length and breadth

Answer 1

Answer:

let the breadth =x

let the length=2x

area=800square

area of rectangle =l×b

800square =x×2x

800square =2x square

x square = 800/2

x square=400

x= 20

So, breadth=20, and

length= 2x

2×20

40

Answer 2

Answer:

Length = 40 m

Step-by-step explanation:

Let the breadth be x

So, length = 2x

According to question,

Area of rectangular mango field = 800m^2

Area = l x b

(2x)(x) = 800

2x^2 = 800

x^2 = 400

x = 20

Breath = 20 m

Length = 2 x  20 = 40 m

Hope this helps you.
