The area of a triangle given the base and height is (1/2)*base*height.
If the base of the triangle is 3 more than the height, the area of the triangle is A = (1/2)*(height + 3)*height
The expression for the area of the triangle is (1/2)*(height + 3)*height

given : base of a triangle is 3 more than twice its height.
Let height of a triangle be 'h' ,
then its base = 2h + 3
Area of atriangle (A) = (1/2) * base * height
=> A = (1/2) * (2h + 3) * h
The expression for area of the triangle is
A= (1/2)*h*(h+3) ---> Answer

"3 more than twice its height"
so...let "h" represent height.
* = multiplication symbol
^ = to the power of...
the basic formula for finding the area of a triangle is
so...our base is "3 more than twice the height"
which is 3+2h
1/2*(3+2h)*h -----------> the answer...
but when I keep going it can become
