#26 times 34# feet

Explanation:

Turn the words you're given into simpler maths terms.

Perimeter = width + length + width + length; or #2W+2L#

#:. "P"= 2W +2L=120#

Length is 8ft more than the width: #L=W+8#

Now substitute into the equation for P to find one variable:

#120=2W + 2(W+8)#
#120= 2W +2W +16#
#104=4W#
#W=26#ft

Sub this value for width back into #L+W+8# to find L:

#L=26+8#
#=34#ft
