A rectangle has a length of 7*n* m and a breadth of 4*y* m. Find

- its area in terms of
*n*and*y*, - its perimeter in terms of
*n*and*y*, - the area of the rectangle if
*n*= 5 and*y*= 7.

4 m

- its area in terms of
*n*and*y*, - its perimeter in terms of
*n*and*y*, - the area of the rectangle if
*n*= 5 and*y*= 7.

(4 m)

- its area in terms of
*n*and*y*, - its perimeter in terms of
*n*and*y*, - the area of the rectangle if
*n*= 5 and*y*= 7.

(4 m)

- its area in terms of
*n*and*y*, - its perimeter in terms of
*n*and*y*, - the area of the rectangle if
*n*= 5 and*y*= 7.
