Refer to Figure P$3\mathrm{.}1$a$.$ Write a MATLAB script that will allow the user to enter the width and height of

the rectangular portion of the shape and will compute the area and perimeter of the shape defined by

those dimensions.

Figure P$3\mathrm{.}1$a

Check: For the dimensions shown, the area will be $757f{t}^2$ and the perimeter will be $111ft.$
