The area of the given parallelogram is 120.
Step-by-step explanation:
Step 1:
The parameters needed to determine the area of a parallelogram are the base length and height.
The base length of this parallelogram is 15 inches while its height is 8 inches.
The area of a rectangle is determined by multiplying the base length with the height.
Step 2:
The area of the parallelogram
Here the base length is 15 inches and the height is 8 inches.
The area of the parallelogram
So the area of the given parallelogram is 120.
Answer:
Option B
Step-by-step explanation:
Let the point O is the origin.
Then the coordinates of the vertices A,B and C will be,
A → (-12, -8)
B → (-8, 0)
C → (-6, -4)
Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,
(x, y) → (kx, ky)
By this rule, coordinates of the vertices of the image triangle will be,
If k = ,
A(-12, -8) → A'(-6, -4)
B(-8, 0) → B'(-4, 0)
C(-6, -4) → C'(-3, -2)
From the given options,
Option B is the answer.
