Answer:
The area of the rectangle is 20 square units
Step-by-step explanation:
Through the x values of the ordered pairs, we can see that the length of the rectangle is 5
Through the y-values of the ordered pairs, we can see that the width of the rectangle is 4
The area can be found by multiplying the length and width, so this means
Given:
Consider the vertices of the triangle are (4,4) (6,7) and (8,0).
The triangle is dilated by a scale factor of 3.
To find:
The vertices of the new triangle after dilation.
Solution:
If a figure is dilated by scale factor k with origin as the center of dilation, then the rule of dilation is:
The given figure is dilated by scale factor 3 with origin as the center of dilation, then the rule of dilation is:
Let the vertices of the triangle are A(4,4), B(6,7) and C(8,0).
Using this rule of dilation, we get
Similarly,
And,
The vertices of the new triangle are (12,12), (18,21), (24,0).
Therefore, the correct option is 4.
