that piece has length = x, width = 14, so area = ?

14x
ganeshie8
  • ganeshie8
area of rectangle is simple length times width so, area = 14x
ganeshie8
  • ganeshie8
yes !

wat about that rectangle, it has length = 13, width = x, so its ares is 13x
ganeshie8
  • ganeshie8
notice that corner there is a little square, its area = x^2

X^2+13x+14x=124?
ganeshie8
  • ganeshie8
so total area of shaded region = x^2 + 14x+13x = x^2 + 27x
ganeshie8
  • ganeshie8
yes, solve that equation

Quadratic equation?
ganeshie8
  • ganeshie8
yup ! u wil get two values, u need to discard one value

Thank YOU!

np :) so wat do u get for x ?
ganeshie8
  • ganeshie8
maybe simply give it to wolfram http://www.wolframalpha.com/input/?i=x%5E2%2B14x%2B13x+%3D+124

I got 4
ganeshie8
  • ganeshie8
it says, x = 4, x = -31 since x cannot be negative (cuz x is distance) x must be 4
ganeshie8
  • ganeshie8
Yes, good work :)

I love wolfram, but I actually worked that one out!
ganeshie8
  • ganeshie8
awesome :) i use wolfram even for doing 2x3 lol

this quadratic looked bit nasty, but ok it gave integer solutions atlest so must be workable manually easily :)
