The painting shown at the right has an area of 240 . What is the value of x?

X =? In.

Take x = 10.2 in. or x = 10 in.

Step-by-step explanation:

Given :

Length = (2x+3) in.

Breadth = x in.

Also, the Area of Rectangle = 240 sq in.

We know that,

Area of Rectangle = length x breadth

240 = (2x+3) x

2x² + 3x = 240

2x² + 3x - 240 = 0

Solving    2x²+3x-240 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B²-4AC

x =   ————————

                     2A

In our case,  A   =     2

                     B   =    3

                     C   =  -240

Accordingly, B²  -  4AC   = 9 - (-1920) = 1929

Applying the quadratic formula :

              -3 ± √ 1929

  x  =    ——————

                     4

 √ 1929   , rounded to 4 decimal digits, is  43.9204

So now we are looking at:

          x  =  ( -3 ±  43.920 ) / 4

Two real solutions:

x =(-3+√1929)/4=10.230 ≈ 10

or

x =(-3-√1929)/4=-11.730

We'll take x = +ve value for calculation of length and breadth.

Therefore,

Length = [2(10.2) + 3 ]

L = 23.4 in.

Breadth = 10.2 in.

OR

Length = [2(10) + 3]

L = 23 in.

Breadth = 10 in.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
