The dimensions in ft will go from 8cm by 4cm to, 21.25ft by 10

1/2 is 0.5 as a decimal. So 8.5 multiplied by 2.5 is 21.25, 4 multiplied by 2.5 is 10.

Answer:

The length is 10 and the width is 21.25

Step-by-step explanation:

You time 2.5 × 4 = 10 to get the width

You time 2.5 × 8 = 20 and 1 half of 2.5 is 1.25.

So you add 20 + 1.25 = 21.25 and that is your width.

So the answer is length is 10 and width is 21.25
