Question

Find the values of x and y.

Answer 1

Answer:

Option A

x=6 , y=9

Step-by-step explanation:

As we can see in the figure that point T is the mid point of rectangle and there are two diagonals QS and PR

So in basic geometry we know that the length of the diagonal from the mid point i.e. Taking the diagonal QS the length of QT and TS would be equal because they are same diagonal which is cut into two parts by point T

Similarly the Length of RT and the length of TP would be same

From all this we deduct that

3x = 2y              ..................(i)

and

y + 3 = 2x           ................(ii)

From equation (i)

3x = 2y

Dividing both sides by 3 the equation becomes

x= $\frac{2y}{3}$                ....................(iii)

Putting this value in equation (ii)

y + 3 = 2($\frac{2y}{3}$)

y+3 =$\frac{4y}{3}$

multiplying both sides by 3

3(y+3)=$\frac{4y*3}{3}$

the equation becomes

3y+9=4y

subtracting 3y from both sides

3y-3y+9=4y-3y

y=9

Putting the value of y in equation (iii)

x= $\frac{2*9}{3}$

solving it

x= $\frac{18}{3}$

x=6

so x=6 and y=9 is answer which is option A
