2) if the area of the frame was 64inches², what would be 2 possible sets of dimensions that could be used to make a frame with that area?

First, if the frame is square then it has equal-length sides. Find the measurement of the sides.
s² = 64
s = √64
s = 8

The first dimension is 8 × 8

Second, if the frame is rectangle, it would have length and width. For example the length is 16 inches.
w = 64/l
w = 64/16
w = 4

The second dimension is 16 × 4
There are more possibilities if the frame is rectangle, but i choose the simplest dimension.

So, the answers are 8 × 8 and 16 × 4
