Given the expressions for width (3x + 1) and length (5x - 2) as well as the formula for the perimeter of a rectangle: 2(5x - 2) + 2(3x +10), we can first solve for the simplified expression of 'x' and then substitute the given value of x = 4cm to find the total distance:
Divide both sides by -5 Sqrt(x) = 3 We want to isolate x to solve for it. The opposite of a square root is a square, so square both sides. x = 9 It can't be -9 because the square root of negative numbers are not real numbers.
