I need help finding area

Question

triangle Help

Answer 1

There are an number of formulas for the area of the triangle. Here are four

1. The most familiar formula using the base b and height h:

     A = bh/2

2. If two of the sides have lengths a, b and form angle of measure θ, then

    A = (ab sin θ) / 2

3. Heron's formula, given that the three sides have lengths, a,b,c. Let s = P/2 = (a+b+c)/2 be the semiperimeter. Then

     A = √[s(s - a)(s - b)(s - c)]

4. If P is the perimeter and r is the inradius then

    A = Pr/2.

Answer 2

There are a few ways to think of the area of a triangle. I think of a rectangle. if the rectangle has height "a" and length "b" the we know that the area for that rectangle is given as "ab" or a times b. Now if we cut the triangle in half from one corner to another corner we see that we have half of that rectangle which in turn is a triangle. Since we have half of that rectangle then we half the "ab" or a times b divided by two as both Bill and Carlos said. 

 

 

Answer 3

The area of any triangle is:

(1/2) b h

where

b is the length of its base

h is the height of the triangle

 

Answer 4

Could you provide more information? A more specific answer will help. Meanwhile...

The area of triangle is calculated by the following formula:

A = (b*h) /2

where:

A = Area  b = base  h = height
