Apply area of the parallelogram formula to solve problems.
1.Imagine your table top as a rectangular surface and calculate its area. Determine how many parallelograms with a base of 8cm and a height of 7cm can fit within this area.
2.What changes in height must be made if we double the base of a parallelogram, keeping the area same?

A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. Find the area of the tile.

1. 34 sq.cm
2. 240 sq.cm
3. 200 sq.cm
4. 120 sq.cm
