Since each one is a square, each side has to be the same length. I know that 12×12 is 144, so for the first square, each side is 12 inches. Then, use the formula to determine the perimeter. 4×12=48, so the first perimeter is 48 inches. For the second, I know that 9×9=81, so each side is 9. 4×9=36, so the perimeter is 36. For the last, each side is 18 inches. 4×18=72, so the perimeter is 72 inches.

denpristay [2]

Answer:

312 employees participated in the training

Step-by-step explanation:

Given;

employee to instructor ratio is 24 to 2

there are 26 instructors for the training

let the total number of instructors be I = 26

let the total number of employees be e = ?

employee to instructor ratio is 24 to 2, e : I = 24 : 2

e : I = 24 : 2 = e : 26

$\frac{24}{2} = \frac{e}{26} \\\\e = 12 *26\\\\e = 312$

Therefore, the total number of employees who participated in the training is 312
