## Area of a triangle

Use "A" for "AREA" "B" for "BASE" and "H" for "HEIGHT"
Here are some bases (B) and heights (H):

Area of a triangle:
```     B x H
A = ------- <== Use this with whole numbers or decimals
2
```

Examples:
 ```1. Base = 8 ft. 8 x 4 32 Height = 4 ft. A = ------- = ---- = 16 2 2 sq. ft. ``` ``` 2. Base = 8.5 ft. 8.5 x 4.5 38.25 Height = 4.5 ft. A = ------- = ---- = 19.125 2 2 sq. ft. ```
Here's another formula that computes the same area:
```     1
A = --- x  B  x  H   <== Use this with fractions
2                   and mixed numbers
```

Fraction Examples:
```1. Base   = 3/5 in.       1     3     1      3
Height = 1/4 in.  A = --- x --- x ---- = --- sq. in.
2     5     4      40
```
```2. Base   = 2 in.         1     2     3     6     3
Height = 3/4 in.  A = --- x --- x --- = --- = --- sq.
2     1     4     8     4  in.
```
```3. Base   = 1 1/2 cm.       1     3     11     33    2 1/16
Height = 2 3/4 cm.  A = --- x --- x ---- =  --- = sq. cm.
2     2      4     16
```
