On a rectangular plot of land with sides of 20 m and 30 m, the foundation for a house has the shape of a rectangle with sides of 10 m and 12 m. What part of the area of the entire plot is occupied by the house?

We calculate the area of the site. The area is equal to the product of the opposite sides of the rectangle.
S = 20 m × 30 m = 600 m2.
Next, we calculate the area of the foundation of the house.
S 1 = 10 m × 12 m = 120 m2.
To find out what part is the area of the foundation, for this we divide the area of the foundation by the area of the site. We write down the solution:
S1 / S = 120 m2 / 600 m2 = 1/5.
This means that the foundation occupies 1/5 of the entire site.
Answer: the foundation occupies 1/5 of the entire site.
