Karo-lina-s [1.5K]

Answer:

Each person would get 1/10 because if you are only taking half of it, the remaining half is still there. The pieces are going to be smaller than 5s or 2s, so it's gonna be divided into 0.1 or 1/10 since there are 5 people. I hope this helps :)

irga5000 [103]

Answer- each width = 10, each length = 21

Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21
