To determine how many days is it until Jack's birthday, we need a conversion factor to convert from weeks to days. We know, as a fact, that in one week there will be 7 days. So, we use this value. We do as follows:
4 weeks ( 7 days / 1 week ) = 28 days until Jack's day
For perimeter Add all of them for the area multiply both side and u would get the answer
4 x 8 = 32
X essentially means “groups of”. So we have 4 groups of 8.
8+8+8+8
We can then add those
16+16
=32
