Alejandra has five hair ribbons measuring 8, 13, 11, 9, and 13 inches long. what is the median length of the ribbons?

The median is defined to be simply the middle number in a data set when all values are arranged in ascending order. So first let us arrange all the values in ascending order:

8, 9, 11, 13, 13

We can see that 11 is the middle number in the data set. Therefore the median is 11.

11

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
