Question

area of triangles and parallelograms. what is the area of triangle gjh? square units. 12 square units. square units.

Explanation:

Step1: Identify base and height

From the graph, for triangle GJH, the base GH is 3 units (from x - coordinate of G = 1 to x - coordinate of H = 4) and the height is 4 units (from y - coordinate of H = 1 to y - coordinate of J = 5).

Step2: Apply triangle area formula

The area formula for a triangle is $A=\frac{1}{2}\times base\times height$. Substituting base = 3 and height = 4, we get $A=\frac{1}{2}\times3\times4$.
$A = 6$ square units.

Answer:

6 square units
