The length of one side of the rectangle is 2400 mm, and the other is 12 times longer.

The length of one side of the rectangle is 2400 mm, and the other is 12 times longer. Calculate the area of the rectangle. The lengths of the sides of the triangle are 1048 mm, 1048 mm and 3 m. Calculate the perimeter of this triangle. The area of the entire apartment is 66 m2. The area of the first room is 14 m2, the area of the second room is 8 sq. m. How many times is the area of an apartment larger than the area of two rooms?

1. The area of the rectangle is S = ab, where a = 2,400 mm, b = 12 * 2,400 mm = 28,800 mm.

Thus, S = 2,400 mm * 28,800 mm = 69,120,000 mm ^ 2 = 69.12 m ^ 2.

Answer: the area of the rectangle is 69.12 m ^ 2.

2. The perimeter of the triangle P is equal to the sum of the lengths of the sides:

P = 1,048 mm + 1,048 mm + 3,000 mm = 5,096 mm = 5.096 m.

Answer: the perimeter of the triangle is 5.096 m.

3. The area of 2 rooms is 14 m ^ 2 + 8 m ^ 2 = 22 m ^ 2, which is less than the area of an apartment in

66 m ^ 2/22 m ^ 2 = 3 times.

Answer: the apartment is 3 times larger than 2 rooms.
