The foundations for the house were laid on a rectangular plot of land with sides of 20m and 30m.

The foundations for the house were laid on a rectangular plot of land with sides of 20m and 30m. The foundation has the shape of a rectangle with sides of 12m and 20m. What part of the area of the entire site will it take?

First, let’s determine the area of this piece of land.

To do this, we multiply the width and length of the site with each other.

We get:

20 * 30 = 600 m2

In a similar way, we determine the area of the foundation for the house.

We multiply 12 and 20 meters.

12 * 20 = 240 m2

To find out what part of the area of the site is the area of the foundation, it is necessary to divide the area of the foundation by the area of the site.

In this case, we get:

240/600 = 0.4 part or 2/5.

Answer: The area of the foundation is 0.4 of the area of the site.
