Question

what is the area of triangle ghj? 5 square units 6 square units 7 square units 12 square units

Explanation:

Step1: Identify base and height

From the graph, \( G(1,1) \), \( H(4,1) \), \( J(4,5) \). Base \( GH = 4 - 1 = 3 \) units. Height \( HJ = 5 - 1 = 4 \) units.

Step2: Apply triangle area formula

Area of triangle \( = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 3 \times 4 \)

Step3: Calculate the area

\( \frac{1}{2} \times 3 \times 4 = 6 \)

Answer:

6 square units
