L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64

Step-by-step explanation:
20 cm by 12 cm
b
i got this wrong
I think it will be less than 69 because the tozal mean is 41 while of A is 69 mean the values has decreased
