Answer:
The dimensions of the dilated image are 60 cm by 32 cm
Explanation:
we know that
The scale factor is equal to 4
The scale factor is > 1 -----> therefore the dilation is an enlargement
To find the dimensions of the dilated image, multiply the original dimensions by the scale factor
New Length=(15)(4)=60 cm
New Width=(8)(4)=32 cm
The dimensions of the dilated image are 60 cm by 32 cm
