Question

If a parallelogram is reduced to have dimensions that are half as long, then the perimeter is one fourth the original length. True or False?

Answer 1

P=2l+2w
2(1/2)l+2(1/2)w=l+w
original perimeter =2l+2w
new perimeter =l+2
\[\frac{l+w}{2(l+w)}=\frac{1}{2}\]

Answer 2

new perimeter (l+w), rather
