Question

area of triangles and parallelograms. what is the area of triangle ghj?

Explanation:

Step1: Identify base and height

From the graph, for triangle \(GJH\), the base \(GH\) is \(4 - 1=3\) units and the height (vertical distance from \(J\) to \(GH\)) is \(5 - 1 = 4\) units.

Step2: Apply triangle - area formula

The area formula of a triangle is \(A=\frac{1}{2}\times base\times height\). Substitute base \(b = 3\) and height \(h = 4\) into the formula: \(A=\frac{1}{2}\times3\times4\).

Step3: Calculate the area

\(A=\frac{1}{2}\times3\times4 = 6\) square units.

Answer:

6 square units
