Step-by-step explanation:

The inclined plane is in the shape of a right triangle, therefore we can use the Pythagorean theorem to find the length of the inclined plane. The formula for this theorem is the following

a^{2} + b^{2} = c^{2}

Where a and b are the two sides and c is the hypotenuse/inclined side. Therefore, we can simply plug in the lengths of the two sides into the formula and solve for c.

a^{2} + b^{2} = c^{2}

7^{2} + 16^{2} = c^{2}

49 + 256 = c^{2}

305 = c^{2}   ... square root both sides

17.46 = c
