Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
Answer:
I'm pretty sure the answer is 48 feet.
Step-by-step explanation:
It can't be any of the negative answers since the question didn't start with a negative number, and it can't be 14 feet since he started with 15 feet, so it has to be 48 feet.

Answer:
± 42.25
Step-by-step explanation:
±6.5^2 = ±42.25
<span>Here, Elaine = Tyler + (-8)
</span>⇒ E<span>laine + 0 + Tyler + 0 = 34
</span>⇒ T<span>yler + (-8) + 0 + Tyler + 0 = 34
And, Tyler = [(34 - (0) - (-8)] / 2
Thus, Tyler = 21
And, Elaine = 21 + (-8)
=13
</span>∴ T<span>yler = 21 & Elaine = 13
