The perimeter of the rectangle is undefined.
But if it did exist, it would be
Explanation:
The formula for perimeter is
The width
#w# is#2sqrt5+5sqrt3#
The length#l# is#3sqrt5 - 4 sqrt3#
Hmm... the length is less than 0 (it is
Let's go ahead and pretend we could have negative sides.
In that case, the perimeter is:
#P = 2(3sqrt5-4sqrt3)+2(2sqrt5+5sqrt3)#
#P = 6sqrt5-8sqrt3+4sqrt5+10sqrt3#
#P = 10sqrt5 + 2 sqrt3#
