Answer 1

Answer:

AB = 31.5 cm

Step-by-step explanation:

AD = 21 cm, DH = 18 cm, DK = 27 cm.

Area of parallelogram = Base * Height

=> AB * DH = AD * DK

=> AB * 18 = 21 * 27

=> 18AB = 567

=> AB = 567/18

=> AB = 31.5 cm

Hence, AB = 31.5 cm

Answer 2

Step-by-step explanation:

FIRSTLY

find the area of the parallegram with DR as height and BC as base

so, Since, AD = 21 cm

therefore BC= 21 cm { ABCD is a parallelogram}

and DR = 27 cm

AREA of ABCD = 21cm*27cm -(1)

SECONDLY

area of ABCD with DH as height and AB as base

DH = 18 cm

AREA OF ABCD = 18cm*AB-(2)

COMPARING (1) &(2)

21cm*27cm=18cm*AB

AB= (21*27) /(18)

AB= 63/2 cm

AB = 31.5 cm
