In C++:

Assume given the following definition of function computeAreaPeri2 that computes the area and the perimeter of a rectangle given its length and width:

void computeAreaPeri2( double len, double wid, double &ar, double &peri ) { ar = len * wid; peri = 2 * ( len + wid ); }

A: Write the sequence of statements to compute and print the area and the perimeter of a rectangle with length 70 and width 45.

B: Write the sequence of statements to read the length and the width of a rectangle and to compute and print its area and perimeter.
