Question

Neha design a rectanglar park whese length is twice its breadth, and the area is 1800sq? do you agree with her? If so find the length and breadth. ​

Answer 1

let the breadth as 'x'

so the length would be 2x

so the area from this equation we get

$2x × x = 1800m^2$

$2x^2 = 1800m^2$

$x^2 = \frac{1800}{2}$

$x^2 = 900m^2$

square root both side

$\sqrt{x^2} = \sqrt{900m^2}$

$x = 30$

so 'x' means breadth is 30 so length is

2×30= 60

Answer 2

Let breadth be x

Therefore Length=2x

L x B = 1800

x X 2x =1800

2 x square is equal to 1800

x square is equal to 1800 / 2

x square is equal to 900

x is equal to square root of 900

x is equal to plus or minus 30

x is equal to 30

since why is double of X therefore it will be equal to 60

check

30 into 60 is equal to 1800 and answer is correct
