Answer to Question 1

The intersection of the VMP and the wage determines the number of workers to be hired. Hence the rectangular area bound by the wage and the number of workers employed at that wage rate give the firm's expenditure on its variable input, i.e. labor. The triangular area above the wage line and below the VMP is therefore the funds that the firm has left to use on its fixed inputs.
