Answer:
The perimeter is 110 cm.
Explanation:
The length of a rectangle is 3x-5 and the width of the rectangle is 2x+7. Find the perimeter.
if we condense that
Perimeter = 2(Length) + 2(Width)
Now we can see how the answer forms. If we plug in our equations from above:
100 = 2(3x + 5) + 2(2x)

100 = 6x + 10 + 4x
