Answer:
The length of each side is 31.5m, 26.5m, 7m
Step-by-step explanation:
Let the length of the first side of the triangle be x meters.
Then, the second side is x-5 meters.
The third side is given as 7 meters.
The perimeter is 65 meters
This gives us the equation:
![65 = x + x - 5 + 7](https://tex.z-dn.net/?f=65%20%3D%20x%20%2B%20x%20-%205%20%2B%207)
![65 - 7 + 5 = x + x](https://tex.z-dn.net/?f=65%20-%207%20%2B%205%20%3D%20x%20%2B%20x)
![63 = 2x](https://tex.z-dn.net/?f=63%20%3D%202x)
![x = \frac{63}{2} = 31.5](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B63%7D%7B2%7D%20%20%3D%2031.5)
The length of each side is 31.5m, 26.5m, 7m
Answer:
The area of the clock ![= 315.41\ inch^{2}](https://tex.z-dn.net/?f=%3D%20315.41%5C%20inch%5E%7B2%7D)
Step-by-step explanation:
We have been given the face of the clock that is ![63\ in](https://tex.z-dn.net/?f=63%5C%20in)
So that is also the circumference of the clock.
Since the clock is circular in shape.
So ![2\pi(r)=63\ inch](https://tex.z-dn.net/?f=2%5Cpi%28r%29%3D63%5C%20inch)
From here we will calculate the value of radius
of the clock that is circular in shape.
Then ![2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in](https://tex.z-dn.net/?f=2%5Cpi%28r%29%3D63%5C%20inch%20%3D%5Cfrac%7B63%7D%7B2%5Cpi%7D%20%3D%2010.02%5C%20in)
Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.
Now ![\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}](https://tex.z-dn.net/?f=%5Cpi%20%28r%29%5E%7B2%7D%3D%5Cpi%2810.02%29%5E%7B2%7D%3D315.41%5C%20in%5E%7B2%7D)
So the area of the face of the clock =![315.41\ in^{2}](https://tex.z-dn.net/?f=315.41%5C%20in%5E%7B2%7D)
