Question

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

Explanation:

Step1: Identify triangle type and formula

This is a right - triangle. The area formula for a right - triangle is $A=\frac{1}{2}\times base\times height$. Here, the two legs (the sides forming the right angle) can be considered as the base and the height. Let the base $b = 4$ meters and the height $h=3$ meters.

Step2: Substitute values into the formula

Substitute $b = 4$ and $h = 3$ into the formula $A=\frac{1}{2}\times b\times h$. So $A=\frac{1}{2}\times4\times3$. First, calculate $4\times3 = 12$, then $\frac{1}{2}\times12=6$. The unit of area is square meters.

Answer:

C. 6 square m
