The answer should be the 1st one.
Just use the quadratic formula and plug in the necessary numbers when requested and work from there.
Consecutive even integers are 2 apart
they are
x,x+2,x+4
total sum is 60
x+x+2+x+4=60
3x+6=60
minus 6 both sides
3x=54
divide both sides by 3
x=18
x+2=20
x+4=22
the ages are
18,20,22
357 centimeters would be your answer, this is because:
21*17=357cm
I hope this helps.
