Paladinen [302]
Let, the width = x
length = 2x - 4

Perimeter = 2(l+w)
Substitute their values, 
72 = 2(x+2x-4)
72 = 2(3x-4)
6x - 8 = 72
6x = 80
x = 80/6
x = 13.3

Lyra and Donna are testing the two-way radios they built for their high school science project. Lyra goes to the top of a buildi
9966 [12]
They will be forming a right triangle. 

long leg is the height of Lyra. 22 meters high from the entrance.
short leg is the distance of Donna. 50 meters from the entrance.
We need to solve for the hypotenuse or the range of communication.

a² + b² = c²
22² + 50² = c²
484 + 2500 = c²
2,984 = c²
√2,984 = √c²
54.63 = c

The range of communication for the two radios is 55 meters.
