Question

A) The ratio of the new area to the old area will be 1:4
B) The ratio of the new area to the old area will be 1:8
C) The ratio of the new area to the old area will be 1:2
D) The ratio of the new area to the old aerie will be 16:1

Answer 1

Answer: 1:4

It doesn't matter what the original side lengths were. If both dimensions are divided by 2, (halved) the Area of the new square will be 1/4 the Area of the original square.

Explanation:

But to prove it: 27×27 = 729 .

27/2 = 13.5 . 13.5 × 13.5 = 182.25

729/182.25 = 4 .or 182.25/729 = 0.25
