Answer:
this answer is going to a 20 out of 100 percent
the answer is C or D
Answer:
D
Step-by-step explanation:
I am confused but thats my guess
16+16+16+9+9=32+16+9+9=48+9+9=57+9=66
The answer is 66
We know that the perimeter of a rectangle is twice the length, plus twice the width.
P = 2L + 2W
We also know that the perimeter is 156.
P = 156
Finally, we know that the width is 12 less than the length.
W = L - 12.
The next thing that we do is substitute the information that we have into the original equation:
P = 2L + 2W
156 = 2L + 2(L - 12)
From this point we start to solve
156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis
156 + 24 = 2L + 2L - 24 + 24
180 = 2L + 2L <--- getting like terms on same sides
180 = 4L <---combining like terms
180/4 = 4L/4 <--- getting like terms on same sides
45 = L <---now we have a value for L
Now we take the known value for L and substitute it in to our equation for W
W = L - 12
W = 45 - 12
W = 33
So now we have Length = 45 and Width = 33.
Answer:
The answers would be 5.42 and 5.1.
Step-by-step explanation:
The diagram shows 5.39, so those answers would be more than the diagram shows.
