ABCD is a r

Answer :

ABCD is a Rectangle.
This means:

AB = DC and AD = BC

(∵ opposite sides of Rectangle are equal)

x + y = 30 .... (1)
x – y = 14 .... (2)

Add (1) and (2) to get,

(x + y) + (x – y) = 30 + 14

⇒ 2x = 44

⇒ x = 22

Putting the value of x in equation (1) to get,
22 + y = 30

⇒ y = 30 – x

⇒ y = 30 – 22
= 8

⇒ x = 22 and y = 8
