This question must be answered using Matlab

6. (8pts) a. Write a function rectpyramidarea to calculate the surface area of a right rectangular pyramid that accepts the base length 1, the base width w, and the pyramid height h as inputs and returns the surface area corresponding to the following equation: W 2 area = lw + I h2 + + w h+ +63* Here are examples of using the function: >>rectpyramidarea (1,1,1) ans = 3.2361 >>help rectocamidarea zectpyramidarea calculates the surface area of a right rectangular pyramid b. (4pts) Write a script to prompt the user for the base length, base width, height of a right rectangular pyramid. Then call the function rectpyramidarea in (a) to calculate the surface area of the right rectangular pyramid and print the surface area with 1 decimal place
