Find the perimeter of the image below: figure qrstu is shown. q is at 2, 0. r is at 4, 5. s is at 8, 7. t is at 6, 4. u is at 10, 3. 25.8 units 26.1units 27.5 units 28.6 units

Hence, the perimeter of the figure is:

(√29+ 2√5 +√13+ √17+√73) units=26.1 units.

Step-by-step explanation:

The perimeter of the figure is the length of all the line segments.

i.e. Line segment QR,RS,ST,TU and QU.

We know that the distance between two points (a,b) and (c,d) is given as:

.

i.e. distance between (2,0) and (4,5) is:

Hence length of line segment QR is: √29 units.

i.e. the distance between (4,5) and (8,7) is:

Hence length of line segment RS is: 2√5 units.

i.e. the distance between (8,7) and (6,4) is:

Hence length of line segment RS is: √13 units.

i.e. the distance between (6,4) and (10,3) is:

Hence length of line segment RS is: √17 units.

i.e. the distance between (10,3) and (2,0) is:

Hence length of line segment RS is: √73 units.

Hence, the perimeter of the figure is:

(√29+ 2√5 +√13+ √17+√73) units=26.1 units

the expected value of the random variable : 0, 1 and 2
