Final answer:When the dimensions of a figure are multiplied by 5, the surface area becomes 25 times larger because the scale factor squared (5^2) is applied to the original area.Explanation:If the dimensions of a figure are multiplied by 5, the surface area will increase by the scale factor squared. This is because surface area is a two-dimensional measurement, and each dimension of the figure is being scaled by 5.For example, suppose that we have a square with a side lengths. The area of the square issxs, which iss^2. If we multiply the side length by 5, the new side length becomes 5s. The new area will then be (5s) x (5s) = 25s^2. As you can see, the new area is 25 times larger than the original area.Applying this rule, if a figure's dimensions are multiplied by 5, the surface area becomes 5^2, or 25, times larger. So the correct answer is C) 25 times larger....
