Which formula gives the area of a triangle with base b and height h?

Explanation:
The area of a triangle is found by taking half of the product of its base and its height. If you lay out a rectangle with the same base and height, its area would be base × height, and the triangle fits exactly half of that rectangle, so the triangle’s area is 1/2 × base × height. Written with symbols, that’s a = 1/2 b h. The other formulas correspond to different shapes: s^2 is for a square, p = sum of all three sides is the perimeter, and a = l × w is for a rectangle.
