Question

ABCD is a rectangle. If AB = 12, BC = 8 ,CD-x+y and DA=x-y
then find
' and y​

Answer 1

Answer:

X=10

Y=2

Step-by-step explanation:

AB=CD BC=DA

12=X+Y 8=X-Y

FROM THESE

X+Y=12

X-Y=8

______

2Y=4

Y=2

X-Y=8

X-2=8

X=10

Answer 2

ANSWER:

x=10

y=2

Step-by-step explanation:

AB =CD,BC =DA....... 1

property of a Rectangle

AB=12 ....... 2

BC=8........ 3

CD=x+y..... 4

DA=x-y....... 5

from 1,2,3,4,5 we get;

x+y=12....... 6

x-y=8......... 7

adding eqn 6&7;

x+y=12

x-y=8

________

2x = 20

x =20/2

x =10

put x=10 in eqn 6

x+y=12

10+y=12

y=12-10

y=2
