To find the ratio of the areas of the two triangles, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
For the smaller triangle:
Base = 5 - 2 = 3
Height = 9 - 3 = 6
Area = 1/2 * 3 * 6 = 9
For the larger triangle:
Base = 12 - 10 = 2
Height = 6 - 2 = 4
Area = 1/2 * 2 * 4 = 4
Therefore, the ratio of the area of the smaller triangle to the area of the larger triangle is 9:4.
Use the image to answer the question.
An illustration shows the first quadrant of a coordinate plane. The x-axis and the y-axis range from 0 to 15. Two right triangles are graphed on the plane. One triangle is formed by connecting points plotted at coordinates left parenthesis 5 comma 9 right parenthesis, left parenthesis 5 comma 3 right parenthesis, and left parenthesis 2 comma 3 right parenthesis. The sides of this triangle are formed by solid lines. The second triangle is formed by connecting points plotted at coordinates left parenthesis 12 comma 6 right parenthesis, left parenthesis 12 comma 2 right parenthesis, and left parenthesis 10 comma 2 right parenthesis. The sides of this triangle are formed by dotted lines.
