Answer: 150,000 = (n - 150)(n + 50)
33,600 = (2w - 40) (w)
<u>Step-by-step explanation:</u>
Let n represent the "number".
then width = n + 50
and length = (n + 50) - 200 --> n - 150
Area = Length x width
150,000 = (n - 150)(n + 50)
************************************************************
Let w represent the width
then width = w
and length = 2w - 40
Area = length x width
33,600 = (2w - 40)(w)
The lower bound is the smallest value that would round up to the estimated value. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.
