Answer:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
Remember that
1m=100cm
8m=800cm
800m=80,000cm

Answer:
The length is 13
Step-by-step explanation:
w+w+l+l= perimeter
if the length is 3m less than twice the width then let's do some math.
42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.
ANSWER:
The surface area of the star is 3.2700 x
square kilometres.
EXPLANATIONS:
Diameter of the star = 1.8083 x
Km.
Surface area of the star = 4![n^{2}](https://tex.z-dn.net/?f=n%5E%7B2%7D)
Where n is the radius of the star.
So that;
n =
= 0.90415 x ![10^{4}](https://tex.z-dn.net/?f=10%5E%7B4%7D)
n = 0.90415 x
Km
Thus,
Surface area = 4 x ![(0.90415*10^{4} )^{2}](https://tex.z-dn.net/?f=%280.90415%2A10%5E%7B4%7D%20%29%5E%7B2%7D)
= 326994889
Surface area = 3.2700 x
![km^{2}](https://tex.z-dn.net/?f=km%5E%7B2%7D)
Therefore, the surface area of the star is 3.2700 x
square kilometres.
