Answer:
The expression of the other side of the rectangle = 2x + 4y + 25
Step-by-step explanation:
The Perimeter of the rectangle is 12 x + 8y
The one side of the rectangle is 4x - 25
Let the other side of the rectangle be S
Now, the PERIMETER OF THE RECTANGLE = 2 ( SUM of BOTH SIDES)
⇒ 12 x + 8y = 2(S + (4x - 25))
or, 12 x + 8y = 2S + 8 x - 50
or, 12 x + 8y - 8x + 50 = 2S
⇒ 4x + 8y + 50 = 2S
or, S = 2x + 4y + 25
Hence, the expression of the other side of the rectangle = 2x + 4y + 25
