Problems leading to quadratic equations

The height of a right-angled triangle is 3 cm more than the width. The area is 10 cm2. Find the width of the triangle.

There is a problem with this problem. I think they want a height of 5 and a width of 2. That would make an area of 10 for a rectangle, but not for half of that rectangle that makes a triangle (why the area of a triangle is bh/2).

This is a quadratic equation i.e. I am supposed to form a quadratic equation from this problem and then solve it, the answer is meant to be found via the quadratic formula.
