=Area of a Triangle=

Area=(1/2)Base*Height A=(1/2)B*H

So where does the 1/2 come from in the formula for area? If we look at a rectangle, we notice that it can be divided into two triangles.

We know that the area of a rectangle is Base*Height. So if we split the rectangle into half (2 triangles) then we divide the area by 2. //Therefore the Area of a Triangle is half of that of a square. A=(1/2)B*H//
