#### Answer

perimeter = $28$ yards

#### Work Step by Step

RECALL: (1) The perimeter of a polygon is equal to the sum of the lengths of all its sides. (2) The opposite sides of a rectangle have equal lengths. This means that the two unknown side lengths are 6 yd and 8 yd. Add the lengths of all the sides to find the perimeter: perimeter = $6+6+8+8= 28$ yd
