To find the length of the inclined plane, we can use the formula for mechanical advantage:

mechanical advantage = (length of ramp)/(height of ramp)

Given that the mechanical advantage is 1.5 and the height of the ramp is 7 ft, we can plug these values into the formula:

1.5 = x/7

To solve for x, we can multiply both sides of the equation by 7:

1.5 * 7 = x

x = 10.5 feet

Therefore, the length of the inclined plane, x, is 10.5 feet.

The answer is B) 10.5 feet.
