Perimeter is #P=14x+2#

Length L
Perimeter P=2(L+B)
Given:
Width #B=5x-9#
Length #L=2x+10#
Perimeter #P=2(5x-9+2x+10)#
#P=2(7x+1)#
#P=14x+2#

14x + 2 feet

Explanation:

Perimeter of a rectangle = 2 (length + breadth)

Length = #2x + 10#
Breadth = #5x - 9#

Perimeter = #2(2x+10 +5x - 9) = 2(7x+1) = 14x +2#
