Answer:
15
Step-by-step explanation:
Let's call Leah's age l and Rachel's age r. We can write:
l = 3r - 2 (1)
l + 3 = 2(r + 3) + 7 (2)
Substituting (1) into (2) we get:
(3r - 2) + 3 = 2(r + 3) + 7
3r + 1 = 2r + 13
r = 12
In 3 years Rachel will be 12 + 3 = 15 years old.

the diameter is the diaagonal of the squar which also makes a right triangle where the diagnal is the hypotnuse
and since it is a square
the legs are equal measure
a^2+b^2=c^2
where legs legnth a and b an hypotnuse legnth c
c=7
a=b
a^2+a^2=7^2
2a^2=49
divide by 2 both sides
a^2=19.5
sqrt both sides
a=√19.5
the legnth of 1 side is √19.5 max or aprox 4.41588 inches
