The yard is 130 feet around.

Explanation:

Assuming the small backyard is a rectangle than you can determine how far around the yard is by using the formula for the perimeter of a rectangle which is #p = (2 xx l) + (2 xx w)# Where #p# is the perimeter, #l# is the length, and #w# is the width.

In this problem we are given the length or #l# as 45 feet. We are also given the width or #w# as 20 feet. Substituting these into the formula and then solving gives:

#p = (2 xx 45 feet) + (2 xx 20 feet)#

#p = (90 feet) + (40 feet)#

#p = 130 feet#
