Question
Find the values of x and y in the following rectangle.

Answer

By property of rectnagle,
Lenghts are equal, i.e., CD = AB
⇒ x + 3y = 13 .....(i)
Breadth are Equal, i.e., AD + BC
⇒ 3x + y = 7 .....(ii)
On multiplying Eq. (ii) by 3 and then subtracting Eq. (i), we get

x = 1
On putting x = 1 in Eq, (i), we get
3y = 12 ⇒ y = 4
Hence, the required of x and y are 1 and 4, respectively.
