Answer:
perimeter of rectangle = 2 (length + breadth)
= 2(9x + 6y + 13x + 2y)
= 2(22x +8y)
= 44x + 16y
Step-by-step explanation:
9x+6y
9-9x+6-9y both side subtract 9
x+(-3)y
x-3y the answer
13x+2y
13-13x+2-13y
x+(-11)y
x-11y .
follow me
2.5
you can use pythag theorem and divide c by two:
-3^2+4^2=c^2
9+16= 25
c=5
however, 5/2=2.5
