Answer:
20 ft
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + w)
Let the width be w
=> 104 = 2(32 + w)
=> 104/2 = 32 + w
=> 52 = 32 + w
=> 52 - 32 = w
=> 20 = w
Hence z
Width of playground is 20 ft
Answer:
No, those are not the correct measurements.
Step-by-step explanation:
Assuming that 9 will equal the hypotenuse we will use the Pythagorean theorem.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
a = 5
b = 3
![5^2 + 3^2= 25 + 9 = 34](https://tex.z-dn.net/?f=5%5E2%20%2B%203%5E2%3D%2025%20%2B%209%20%3D%2034)
Well ![9^2= 81](https://tex.z-dn.net/?f=9%5E2%3D%2081)
So...that doesn't quite work out.
Let's change our equation to double check.
![c^2/a^2= b^2](https://tex.z-dn.net/?f=c%5E2%2Fa%5E2%3D%20b%5E2)
![9^2/5^2 = b^2\\\\81/25 = 3.25](https://tex.z-dn.net/?f=9%5E2%2F5%5E2%20%3D%20b%5E2%5C%5C%5C%5C81%2F25%20%3D%203.25)
Once again, that doesn't work out.
So the final answer is, no. Those are not the correct measurements.
