Question

what is the area of triangle lmn? 3 square units 4 square units 6 square units 8 square units

Explanation:

Step1: Find the base and height

From the graph, assume \( LP \) as the height. \( LP=3 - (- 1)=4\) units. The base \( PM = 2\) units.

Step2: Use the area formula for a triangle

The area formula for a triangle is \(A=\frac{1}{2}\times base\times height\). Substitute base \( = 2\) and height \( = 4\) into the formula: \(A=\frac{1}{2}\times2\times4\).

Answer:

\(4\) square units. So the answer is \(4\) square units.
