Question 1015718
If you let x = the width of the triangle then the length = 2x+5
*[illustration area_question_1]
 
You know that the area is 33 therefore you need to multiply the width and length together.
 
x(2x+5)=33
2x^2+5x-33=0

Solve this quadratic to find the answer (Remember that width and length cannot be negative).
