I am assuming you do not mean The length of a triangle and you mean The length of a rectangle because the answer you given are the formula for the perimeter of a rectangle. With that said, the answer is D<span>.2w+2*(3w)112
The perimeter of a rectangle can be found by the following equation:
2L + 2W = P
OR
P = 2L + 2W
The equation </span>P = 2L + 2W is read perimeter = 2 times Length + 2 times width
The Question:
<span>The length of a rectangle is three times its width.if the perimeter is at its most 112 centimeters ,which is the greatest possible value of the the width.
</span>
The length of a rectangle
This means the perimeter
is
The word is means to use an equal sign
three times its width
This means 3 times w or 3w
The w = width
perimeter is at its most 112
This means <=
<= means less than or equal to
Ok so lets look at our equation
2L + 2W = P
2w + 2(3w) <= 112
X = quarters
y = dimes
0.25x + 0.10y = 6.95 or 25x + 10y = 695
x + y = 44
25x + 10y = 695
25 (x + y = 44)
25x + 10y = 695
25x + 25y = 1,100
-15y = -405
y = 27 dimes
and 17 quarters
Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w
1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in
l= w+5
l= 6+5
l=11 in
A= lw= (11)(6)= 66in²
Answer:
Area of rectangle is 66 in².
Answer: 32 is the answer

Answer:
Step-by-step explanation:
<B=90-47=43
AB/BC=sin 47
BC=AB/sin 47=18/0.731=24.6 nearly
AC/AB=Tan 43
AC=18 tan 43=16.8 nearly
