write an expression for the area of the following
Triangle area is 27cm squared with a height of 6cm
3x+4cm
---------------------------------------------------------
How the expression 3x + 4 cm relates to the triangle area?
You missed to explain it.
-------------------------------------------
Comment from student: The area of the triangle is 27cm squared so I know the square area is 54 
with the height of the traingle is 6cm. So the base would be 9 cm but ive got to write an expression to find what the x is 3(X) +4 
-------------------------------------------
My responce: Still unclear: how 3x + 4 relates to the area of the triangle, or to its base, or to its height.
In other words: what is the rational to create an equation for x?
If you have an assignment, then reproduce it here word by word.
