Question 565637: The base of a triangle is 10x units. The height of the triangle is 1 unit more than a tenth of the base. Given the area of the triangle is 100 square units, what is the length of the base?

Let 'h' be the height and 'b' the base. The area is (1/2)bh, so (1/2)bh=100. Also, h=(b/10)+1. Therefore (1/2)b[(b/10)+1]=100 and b=40 [in the form "10x" it is 10*4].
