Let Original rectangle has length L and Width W.

Perimeter = 18 inches

→2(L+W)=18

Dividing both sides by 2,we get

L+W=9  ........(1)

Now, new rectangle is formed by doubling the width Wand tripling the length L.

New length=3 L

New Breadth=2W

New perimeter=46 inches

→2(3 L+2W)=46

Dividing both sides by 2, we get

3L+ 2W=23

→L=9-W  [Using 1]

Substituting in (2), we get

3(9-W)+2W=23

27-3W+W=23

W=27-23

W=4

and L=9-4=5 inches

So, Original rectangle has Length=5 inches, and Width=4 inches

La of sine:

sinC/c = sinB/b==> sin  37°/8 = sin B/12 ==> sin B = 0.903


arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then

sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
