12. Area of a trapezium = 1/2h(a+b)
50 = 1/2(2x(x + x+10))
50 = x(2x +10)
50 = 2x^2 + 10x
2x^2 +10x - 50 = 0
x^2 + 5x - 25 = 0
So if you put this into the quadratic formula (-b + root(b^2 - 4ac))/2a
You should get x = (-5+5root(5))/2
You then substitute this value into the height 2x to get your answer.
Make sense?
13. I have the same textbook and it comes with an online "Active Book" which has a "solution bank" with full worked solutions for every question in the book. Details of how to access this are on the inside of the front cover
