Question

Previously, you learned how to find the area of a rectangle. In this lesson, you will learn how to find the area of a parallelogram.Use what you know to try to solve the problem below.

Kenji and Alec are making paper kites for a kite fight. Kenji's kite is a rectangle and Alec's kite is a parallelogram that is not a rectangle. Each boy draws a model of his kite on grid paper. Does Alec's kite use more paper than Kenji's kite?

Answer 1

To find the areas of the kites, you need to know the dimensions of both the rectangles and parallelograms. You can compare their areas by writing a ratio of the two.

Step-by-step explanation:

To find the area of the parallelogram, you multiply the base by the height. Kenji's kite, being a rectangle, has a base and height that are equal, so the area is base multiplied by height. Alec's kite, being a parallelogram, also has a base and height. So, to compare the areas of the two kites, you need to find the base and height of both kites and then calculate their respective areas.

Once you have the areas of the two kites, you can compare them by writing a ratio of the two areas. If Alec's kite has a larger area, then the ratio will be greater than 1. If Kenji's kite has a larger area, the ratio will be less than 1.

Therefore, you need to know the dimensions of both kites in order to determine which one uses more paper.
