Math measurements

Question

Design 2 rectangular pizzas both with an area of 64 square inches but with different perimeters

Answer 1

LW = 64 in^2

L= 64/W

Perimeter = 2(L+W)= 2(64/W + W) = 2W + 128/W)

where L= length, W= width and P= perimeter

possible dimensions are

W L P

16 4 40

32 2 68

or what are pretty much the same

2 32 68

4 16 40

and an infinite number of other dimensions,

such as

W= 6.4 and L=10 with P=32.8

but everything else does not involve two integers, just fractional lengths or widths

or both fractions.
