Answer:

top one is 48 cm, bottom one is 17.5in.

Step-by-step explanation:

From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.
