Question

Help me.
Is "A" or "B" right?​

Answer 1

When scaling shapes, the perimeter scales with the same constant, while the area scales quadratically.

So, if your scale factor is 1/4, the perimeter of the new shape will be 1/4 of the original perimeter, while the area of the new shape will be 1/16 of the original area.

This implies

`p(E'F'G'H') = (1)/(4)p(EFGH) = (1)/(4)\cdot 40 = 10`

`A(E'F'G'H') = (1)/(16)A(EFGH) = (1)/(16)\cdot 96 = 6`
