Answer:

Option A. 3

Step-by-step explanation:

we know that

The square has 4 equal sides

we have

2x-7 ----> equation A

3y-9 ----> equation B

y-1 ------> equation C

2y-5 ----> equation D

Find the value of y

Equate equation B and C or equation B and D or equation C and D

I choice equation B and C

3y-9=y-1

3y-y=-1+9

2y=8

y=4

Find the length of the square side

Substitute the value of y in equation B or C or D (the result must be the same)

equation B

3y-9

3(4)-9=12-9=3

therefore

The length side of the square is 3 units

Note The value of x does not need to be calculated
