Question

what is the area of the triangle below? triangle image with legs 3 meters and 4 meters a 12 m b 12 square m c 6 square m d 6 m

Explanation:

Step1: Recall the area formula for a right - triangle

The area formula for a right - triangle is \(A=\frac{1}{2}\times base\times height\). Here, the base \(b = 3\) meters and the height \(h=4\) meters.

Step2: Substitute the values into the formula

Substitute \(b = 3\) and \(h = 4\) into \(A=\frac{1}{2}\times b\times h\). We get \(A=\frac{1}{2}\times3\times4\).
First, calculate \(3\times4 = 12\). Then, \(\frac{1}{2}\times12=6\). The unit of area is square meters.

Answer:

C. 6 square m
