Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:
P= 2L + 2W and A= L x W
P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)
P= 12.8 cm
A= 3.2 x 3.2
A= 10.24 cm^2
In this question, <span>Karen measures the garden width result in 44.25 m while it's actual width is 45.5m. Then the amount of error that the Karen did would be: 45.5m-44.25m= 1.25m
The percent error would be:
</span>percent error = amount of error/ actual measurement
percent error = 1.25m/ 45.5m *100%=2.7%
To get your answer, you simply add $85 plus 3 percent. This gives you 87.55
Hope this helps!
