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
