Question

Find the values of x and y in the following rectangle​

Answer 1

Answer:

x+y = 5

Step-by-step explanation:

13 = x × 3y

and

7 = 3x × y

perimeter = 2 x (l+b)

2 x (7+13)

2 x 20

40

perimeter by the equations

2 x (x+3y + 3x × y)

2 x (4x + 4y)

so

40 = 2 x (4x + 4y)

40/2 = 4x + 4y

20 = 4(x + y)

20/4 = x + y

5 = x+ y
