Rooms 4, 45 meters and width 3, 25 meters. What is the area of one room?

Firstly, it should be noted which formula can be used to determine the area of a rectangle for the given parameters:
S = a * b,
where S is the area of the rectangle;
a – the length of the rectangle;
b is the width of the rectangle.
Let’s use the above formula to calculate what the area of the rectangle is equal to c a = 4.45 m and b = 3.25 m:
S = a * b = 4.45 * 3.25 = 14.4625 (m 2).
Let’s round the resulting value to hundredths:
14.4625 = 14.46 (m 2).
Answer: the area of the room is 14.46 m 2.
