A local playground is rectangular and has an area of 76.5 square meters. One side of the playground is 10 meters long. Maria say
s, "The length of the other side is the quotient of 76.5 and 10, so move the decimal point in 76.5 two places to the left because there are two digits in the number 10." Explain and correct Maria's error.
Maria's mistake was that she wanted to move the decimal point 2 places to the left, when she should have moved it 1 place, since that is the number of zeros that the number 10 has.
To find the length of the rectangle, we simply divide the area by the width
The awnser is 1000 because 60 miutes in an hour, 50 mouse traps every half hour so 100 mouse traps an hour multiply that by 10 and you get 1000, i think.
