If bobby has three more than double the amount of jelly beans that marcus has and if marcus has 30 jelly beans, then bobby will have 63 jelly beans.
We look for the dimensions of the first rectangle:
For the length:
(2/6) L = 180
L = (6/2) * (180)
L = 540
For the width:
(3/5) W = 90
W = (5/3) * (90)
W = 150
We look for the dimensions of the new rectangle:
For the length:
L '= 540-150
L '= 390
For the width:
W '= (1/3) * (390)
W '= 130
Answer:
The dimensions of the new rectangle are:
L '= 390
W '= 130
We will do multiplication, 270x0.9 to find out how many rabbits grow in the area each month. Using that number we will multiply it by 12 because the problem is asking us to find the number of rabbits grown in the are in one year. Our final answer would be 292.
