Question

In a square ABCD, AB=x+y CD=2x-y and perimeter is 36 then y=?

Answer 1

Answer:

3

Step-by-step explanation:

for square, all sides are equal

so, x+y = 2x-y

perimeter = 4(AB) = 36

so, AB = x+y = 9

so, x = 9-y

2x-y = 2(9-y) - y = 18-2y-y = 9

18-3y = 9

y = 3

Answer 2

Answer:

2(x+y)+2(2x-y)=36

2x+2y+4x-2y=36

6x=36

x=6
