The following figures GUNS and RUNS are parallelograms
Find x and y (Lengths are in cm)
(i) 
(ii) 
(i) We know that the lengths of opposite sides of a parallelogram are equal to each other
GU = SN
3y − 1 = 26
3y = 27
y = 9
SG = NU
3x = 18
x = 6
Therefore, the measures of x and y are 6 cm and 9 cm respectively
(ii) We know that the diagonals of a parallelogram bisect each other
y + 7 = 20
y = 13
x + y = 16
x + 13 = 16
x = 3
Hence, the measures of x and y are 3 cm and 13 cm respectively
