Question

Abcd is a rectangle of side 30cm 14 cm x + y and x minus y find the value of x and y

Answer 1

X=22,y=8

Step-by-step explanation:

In rectangle opposite sides are equal

X+Y=30--1equation

X-Y=14--2equation

2x=44

X=22

by1we get

y=30-x

y=30-22=8

Answer 2

Answer:

• X=22
• Y=8

Step-by-step explanation:

• LET AB=30

• BC=14
• CD=X+Y
• AD=X-Y
• AB = DC as opposite sides of a rectangle are equal
• SIMILARLY BC=AD
• AB=DC
• 30=X+Y  .............(1)
• BC=AD
• 14=X-Y...............(2)

BY ELIMINATION METHOD

                X+Y=30

             +  X-Y=14

                 2X=44

• X=44/2
• X=22
• AS X+Y=30 BY ..........(1)
• 22+Y=30
• Y=30-22
• Y=8
