Answer: 740
You can answer the question using proportions
The proportion:
222/x = 30/100 (in fraction form)
This will come out to:
22200 = 30x
22200 dived by 30 is 740
x = 740
I hope this somewhat helped
If the first rectangle has length, l, and width w then its perimeter is given by the following relation
2l+2w=72 divide by 2 on both sides so that the relation now becomes l+w=36
If l and w are scaled by a factor of 3.5, the new measurements of your resulting rectangle will 3.5l+3.5w-->3.5(l+w)
