Answer:
Hence, in matrix from it could be written as:
R'=24/8=[24,8]
Step-by-step explanation:
It is given that:
The matrix R=12/4 i.e. R=[12,4] represents the length of 12 in. And the width of 4 in. of a rectangle.
If matrix multiplication is used to double the length and width of the rectangle.
i.e. the length of rectangle will get doubled so that the length will be=12×2=24 inches.
and similarly the width of the rectangle will get doubled and hence width of rectangle will be=4×2=8 inches.
Hence, in matrix from it could be written as:
R'=24/8=[24,8]
