The perimiter is 4 times 1 side
currently, it is 9 times 4 or 36
increased by 3
I think y mean times 3
so 9*3=27
new perimiter is 27*4=108
how much larger is it?
108-36=72
it is 72cm larger
it is the first answer
(it isn't cm² because that is for area and we are calculating perimiter)
This is all percentages so...
4/9 = 44%
2/7 = 29%
1/10 = 10%
Total = 83%
So 17% of 630 is left over which = 107
Than answer you looking for is I think B
Answer:
2
Step-by-step explanation:
2x(5+4)=(_x5)+(_x4)
lets start with 2x(5+4)
(5+4)=9
so we are left with 2x9
2x9=18
so now we have 18=(_x5)+(_x4)
lets try 2 for the blank spaces
18=(2x5)+(2x4)
2x5=10
2x4=8
10+8=18
2x(5+4)=(2x5)+(2x4)
It worked! Hope this helps :)
