Find out the area of a rectangular plot if its seventh part is 29 sq.m.

You need to solve problems with interest. Let’s use proportioning for this.
It is known that 29 m ^ 2 is the seventh part. We will take this area as 1/7. The entire area will be denoted as 1.
Let’s make the proportion:
29 = 1 \ 7;
x = 1.
Solve the proportion using the diagonal method by multiplying each diagonal.
1/7 * x = 29;
Find x by freeing it from the coefficient. To do this, we divide both sides of the equation by the coefficient at x (i.e., by 1/7).
We get:
x = 203 m ^ 2.
Answer: The whole area is 203 m ^ 2.
