The length of a rectangle is three times its width. if the perimeter of the rectangle is 64 cm, what is the area?

before area, we need to calculate length & width

let, width = x

length = 3x

so, 64 = 2(3x+x)

8x = 64

x = 8 (width)

3x = 24 (length)

So, area would be: 24 * 8 = 192 cm²

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
