Question

ABCD is a parallelogram ab and BC are adjacent sides with a b equals to 20 centimetre BC equals to 2 X + 3, CD = 5y and Da = 15 cm find x, y​

Answer 1

Since it is a parallelogram

so,

AB = CD AND BC= DA

now we get

2x + 3 = 15

so,

2x = 12

so x=6

and 5y = 20

so y = 4 ansss

Answer 2

Answer:

Step-by-step explanation

Opposite sides if parallelogram are equal

Henxe

AB = CD

=>20 = 5y

=>y = 20/5

y = 4 cm

Similarly BC = DA

2x + 3 = 15

=> 2x = 15-3 = 12

x = 12/2

x = 6 cm
