Question

ABCD is rectangle with sides AB = x + y , BC = x - y ,CD = 30cm and AD = 14cm respectively find the values of x and y

Answer 1

Answer:

x = 22 y = 8

Step-by-step explanation:

AB = DC = 30

therefore x + y = 30.......1

AD = BC = 14

hence x- y = 14.......2

adding equation 1 and 2 we get

2x = 44

x = 22

substituting value of x in equation 1

22 + y = 30

y = 8

Hope it is helpful for you!!

Answer 2

Step-by-step explanation:

AB = CD

BC = AD

So, AB = x + y = 30 cm

and

BC = x - y = 14 cm

So the answer we should make as combinations of no.s that have sum as 30 and difference as 14 like 15,15; 16,14; 17;13. ........

Like doing this you will end up getting no.s 22 and 8

As 22+8 = 30

22-8 = 14

so, this will be the answer.
