Answer:
<h2>The dimensions of the third blanket are 7.5 feet by 6 feet.</h2><h2>All the blankets are similar.</h2>Step-by-step explanation:
The size of the first blanket is 2.5 feet by 2 feet.
Shannon wants to enlarge the first blanket by scale factor 2 to make the second blanket.
Hence, the size of the second blanket will be feet by
feet.
Again she enlarged the second blanket by a scale factor 1.5 to make the third blanket.
Hence, the size of the second blanket will be feet by
feet.
Enlargement only changes the size of the blanket, it does not change the shape of the blanket. Hence, all the blankets will be similar.
