(i) 3y – 1 = 26 [In a parallelogram opposite sides are of equal length]

3y = 26 + 1

Y =

Y = 9 units

3x = 18 [In a parallelogram opposite sides are of equal length]

x =

x = 6 units

(ii) y – 7 = 20 [In a parallelogram diagonals bisect each other]

y = 20 + 7

Y = units

x-y = 16 [In a parallelogram diagonals bisect each other]

x -27 = 16

x = 16 + 27 = 43 units
