Calculate the area of the living room on a scale of 1: 200 if the size of the living room is 3 * 3

To solve this task, it is necessary to express the area of the living room on a scale;
Consider this task and analyze it;

By the terms of the assignment, we know the natural size of the living room, and so the hedgehog scale in the torus must indicate the area of the living room;

For a further solution, we will find the real area of the living room;

S = a * b = 3 * 3 = 9m2;

Let’s remember what scale is;

Scale is the ratio of lengths and areas on paper to actual dimensions;

Since we know the ratio (scale) and real dimensions, we find the area;

Smas = 9/200 = 0.045cm2.
