the perimeter of a rectangular field is 326 yards. if the width of the field is 75 yards, what is its length?
Rina8888 [55]

P=326 yards

Width= 75 yards

Perimeter= 2 (width + Length)

326 yards = 2 ( 75 yards + Length)

326 / 2 = 75 yards + length

163 yards = 75 yards + length

163 yards - 75 yards = Length

Length = 88 yards
