How do you find the area of a triangle and please show examples

Answers

Answer 1

Answer: to find the area of a triangle, u multiply its base and height, then divide by 2.

the formula for area of a triangle is:
A= B(base)h(height)/2

Answer 2

Answer: There are several ways to find the area of a polygon, but because you're in middle school, you'll most likely use; A = 1/2b * h; where A = area, b = base, and h= height.

Say you have a triangle, the bottom of it is 4 meters and it is 6 meters tall this is not the same thing as a side length. You would divide 4 by 2, which is the same thing as as multiplying by 1/2, and multiply it by 6.

So A = 1/2*2*6
A = 1 * 6
A = 6

25% percent
10/40 is also 1/4 simplified.
1/4 as a fraction is 25%, 25 times 4 equals 100.

OR

Use 1/4, but divide 1 by 4(fraction is also division)
You get 0.25
Turn this into a percent by moving the decimal point to the right 2 times.
The answer is 25%

4% i think im not completely sure but i did alot of work and i pretty sure thats correct
