They both have the same slopes:)

In order to find it, add 20 and 3. That equals 23 and divide by two. It’ll equal 11.5
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
The two short sides must be longer than those required in an isosceles right triangle. The ratio of side length to hypotenuse length in a 45°-45°-90° triangle is 1 : √2. So, such a triangle requires side lengths of 30/√2 ≈ 21.213 inches. Its perimeter will be about
... (30 +21.213 +21.213) in = 72.426 in
Since the perimeter needs to be slightly longer than that for the triangle to be acute, the smallest possible perimeter is ...
... 72.43 in
