Perfect squares are n² where n is a whole number
whole numbers are like 0,1,2,3,4,5,6, etc
no decimal or fractions
we can do that be looking at the perfect squares we know
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
etc
so we see 47 is between 6² and 7²
therefor, for n²=47, n is between 6 and 7 and is therfore not a whole number
that makes 47 not a perfect square
Area of circle is about 50.30 inches squared.

Answer:
d=104
Dasha's garden had 104 originally
Step-by-step explanation:
let d for dasha and a for Anna
d=4a
a=d/4
d-39=a+39
d-39=d/4 +39
d-d/4=39+39
3/4 d =78
3d=4*78
d=(4*78)/3
d=312/3
d=104
Dasha's garden had 104 originally
