Find the perimeter of the following shape:
3.6cm
3cm
7.2cm

13.8

Step-by-step explanation:

3.6 + 3 + 7.2 = 13.8cm

when finding perimeter of shapes always add them up

btw when I typed 13.8 into mathswatch and checked it it was corrected and 13.6 was not but whoever already answered it was close just a miss calculation

hope this helps

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
