Solution:

It is given that length of a rectangle is 3 more days than than twice its width. The perimeter of the rectangle is 42 centimeters.

So,

  • Perimeter of Rectangle = 42 cm

Let Required Breadth of Rectangle be x

  • Then, Length of Rectangle = 2x + 3

Now, We have ;

Perimeter of Rectangle = 2(l+b)

Perimeter of Rectangle = 2(2x+3+x)

42 = 2(3x+3)

42 = 6x + 6

42 - 6= 6x

36= 6x

x = 6 cm

  • So, Length of Rectangle = 2x + 3

Length of Rectangle = 2(6) + 10

Length of Rectangle = 22 cm

1(1 - 4x + 4x²) - 4x(1 - 4x + 4x²) + 4x²(1 - 4x + 4x²)
1(1) - 1(4x) + 1(4x²) - 4x(1) - 4x(-4x) - 4x(4x²) + 4x²(1) - 4x²(4x) + 4x²(4x²)

1 - 4x - 4x + 4x² + 16x² + 4x² - 16x³ - 16x³ + 16x⁴
