Answer 2

If you double every dimension, you're doubling the perimeter...here's why


P = 2(L + W) ... Start with the perimeter of a rectangle formula

P = 2(2L + 2W) ... Double each dimension

P = 2*2(L+W) ... Factor out 2

P = 4(L+W) ... Multiply

Notice how we go from 2(L + W) to 4(L+W)

So we doubled the original perimeter
