Find the area of a triangle with a base length of 3 units and a height of 4 units. 3 square units 6 square units 7 square units
yan [13]

For this case we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the data of the statement we have:

b = 3 \ units\\h = 4 \ units

Substituting in the formula we have:

A = \frac {3 * 4} {2} = \frac {12} {2} = 6 \ units ^ 2

So, the area of the triangle is6 \ units ^ 2

Answer:

6 \ units ^ 2
