Question

the breadth of a rectangle room is two - third of its length. If the area of the room is 2400 m/2 . find the length of the room I will mark as brainliest who ever answer's first​

Answer 1

Answer:

60 m

Step-by-step explanation:

Let the length of field = X

Breadth is 2/3 of lengtg = Xx2/3= 2X/3

Area = 2400m^2

Length of rectangle = Area /breadth

$x = \frac{2400 }{ \frac{2x}{3} } \\ x = \frac{2400}{1} \times \frac{3}{2x} \\ {x}^{2} = 3600 \\ x = \sqrt{3600} \\ x = 60m$

Answer 2

Answer:

length=60m

Step-by-step explanation:

let the length be $x$

breadth=$\frac{2}{3} x$

area=2400 $m^{2}$

area=length*breadth

$2400=\frac{2x}{3} *x\\2400=\frac{2x^{2} }{3}\\2x^{2} =2400*3\\2x^{2} =7200\\x^{2} =\frac{7200}{2}\\x^{2} =3600\\x=\sqrt{3600} \\=60m$
