B*H (base*height) divided by 2
Q. base=4 height=5 What the area of this triangle?
A. 4*5=20 20 divided by 2=10
the reason the formula is B*H divided by 2 is cus a triangle put next to another triangle is a square and a squares formula is B*H so sence a triangle is half a square that just means you have to do the same formula but just cut it in half. find a right angle on the triangle and figure out the height and base of the right angle then multiply then divide by 2.

Area of a triangle: 0.5*base*perpendicular height
length times width times height
The formula for finding the area of a triangle is base multiplied by height divided by two(B*H/2)Made by: Christine Ayoh
Area of Triangle= 1/2(ab) You must multiply length b and length a together and then half it.
Probably Heron wanted a way to calculate the area of the triangle.
