a rectangle is drawn so the width is 17 inches longer than the height. if the rectangle's diagonal measurement is 53 inches, find the height.



Answer :

The height is 45 width.

What is rectange?

  • A quadrilateral with four right angles is a rectangle.
  • It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°).
  • A square is a rectangle with four equal sides.

solving-

  • Let the height be "x".
  • Then width = "x+17".
  • Pythagoras:
  • x^2 + (x+17)^2 = 53^2
  • x^2 + x^2 + 34x + 289 = 2809
  • 2x^2 + 34x - 2520 = 0
  • x^2 + 17x - 1260 = 0
  • x = [-17 +- sqrt(17^2-4*-1260)]/2
  • x = [-17 +- sqrt(5329)]/2
  • Positive solution:
  • x = [-17+73]/2
  • x = 28 (height)
  • x+17 = 45 (width)

Hence, The height is 45 width.
