The area of the rectangle is 2133m2. Its sharina is 9m. Find the length of another rectangle with the same width, but the area is 3 times smaller.
First, we find the area of the second rectangle. It is known that it is 3 times less than the first one.
S = 2133 m2 ÷ 3 = 711 m2.
Now let’s find the length of the second rectangle, which is 9 m wide.
a = 711 m2 ÷ 9 m = 79 m.
Answer: the length of the second rectangle is 79 m.
