Question

Two squares have areas of 4 cm?

and
16 cm?. What is the ratio of the side length of
the smaller square to the side length of the
larger square?

Answer 1

1/2

Explanation:

First square area = 4cm^2, thus the side length is 2cm

Second square area = 16cm^2, thus the side length is 4cm

This gives a ratio of 2/4, simplifying yields 1/2
