To solve this task, you need to make an equation. Let one piece be x, then the length is 7x and the width is 5x. Knowing that the width of the rectangle is 6 meters, let’s make an equation.
5x = 6;
x = 6/5;
x = 1.2.
The length of the room is 1.2 * 7 = 8.4 meters, the width is 5 * 1.2 = 6 meters. The area of a rectangle is equal to the product of length and width. S = a * b, where a is the length and b is the width. Let’s calculate what the area of the room is equal to.
S = 5 * 8.4 = 42 sq.m.
Answer: 42 sq.m.
