Answer:
Step-by-step explanation:
Equation : 165 = 102 + 1.4K
Define: K is # of kilometers
Solve: 63 = 1.4k, so k = 45
Final answer: 45 kilometers
Answer:
2/5
Step-by-step explanation:
Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

We see that the shape is made up of 2 shapes:
trapezoid and triangle
(trapezoid is on top of upside down triangle)
area of trapezoid=(1/2)(b1+b2)(h)
area of traignel=(1/2)(b)(h)
area of trapezoid
b1=14
b2=18
h= ok so total height=17 and 12 is taken up by triangle os therefor h=17-12=5
A=(1/2)(14+18)(5)
A=(1/2)(32)(5)
A=(16)(5)
A=(80)
now area of triangle
H=12
B=18
A=(1/2)(18)(12)
A=(9)(12)
A=108
add
80+108=188
total area=188mm^2
