<PRE><B>Question 919552</B>
The area of a triangle is 34 cm^2. If the base of the triangle is increased by 5 cm, the area of the triangle would be 51cm^2. How long is the base of the triangle? 
-----------------
Area = (1/2)(base)(height)
-----
Original Area:: 34 = (1/2)(b*h)
b*h = 68
----------------------
New Area::
51 = (1/2)(b+5)h
102 = bh + 5h
102 = 68 + 5h
5h = 34
h = 6.8
-----
Ans: b = bh/h = 68/6.8 = 10 cm
