Question

the area of a rectangular field is 30479.805 square unit.its length is twice its breadth.then the length is options are 246,246.9,247 and 245.9

Answer 1

Step-by-step explanation:

Area of rectangular field = 30479.805

we know,

Area of rectangle

= length x breadth

As we have given condition

l = 2b

therefor,

30479.805 =( length = 2b ) x b

30479.805 = 2 b x b

30479.805 = 2b²

(30479.805 / 2) = b²

15,239.9025 = b²

123.45 = b

length = 2b

= 2 x ( 123.45)

= 246.9

therefor the length of rectangular field is 246.9 unit

Answer 2

$\huge \bold \red{hello}$

welcome to the concept Of Mëãšùŕëmèñť.

Things to remember :

Area of rectangle = length x breadth

Let us assume length = l

and breadth = b

then,

.:. l = 2b

30479.805 =( 2b ) x b

30479.805 = 2b x b

30479.805 = 2b²

30479.805 / 2= b²

15,239.9025 = b²

b = 123.45

We know that :

length = 2b

= 2 * ( 123.45)

= 246.9 units

Hence, Length = 246.9 units

Breadth = 123.45 units
