perimeter of a rectangle is 2(l+w)
so 14cm then you need it to be in meters so 100cm=1m
.14m then for how much it is 1.2 per meter so divide both the meters and dollars by 7.14285714286 and you get
it should cost $0.168 to fence the plot
Answer:
348
Step-by-step explanation:
A=2(wl+hl+hw)
2(6·9+8·9+8·6)=348
76/9 = 8.444444444444 > 8.0 or 8.45
Answer:

To solve this you first expand the brackets.
4x^2 - 20x + 25 = 49
Then make it equal 0.
4x^2 - 20x - 24 = 0
Now solve the quardratic.
x^2 - 5x - 6 = 0
(x - 6)(x + 1) = 0
x = 6 or x = -1
