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)
Answer:
B. Add 115+500 then subtract 3
C. Add 112+500
Step-by-step explanation:
Any strategy that gives a sum of 612 will work. Strategy A gives a sum of 602, so is not useful.
The appropriate choices are B and C.
B: 115 +497 = 115 +(500 -3) = (115 +500) -3
C: 115 +497 = 115 +497 -3 +3 = (115 -3) +(497 +3) = 112 +500
67/1.34=50
Therefore $67=£50
