2)The perimeter and area must be the same.How many different flower beds can the gardener make 1)if one of the side is 3 unit less than the other side.2)if both the sides are of same length.

2 answers

1)1-1 and 4 (i can only think of this)
2)1-2 and 2
(1) 2(x + x-3) = x(x-3)
x = 1 or 6
But x=1 isn't viable, so only x=6

(2) 2(x+x) = x^2
x = 4
