One side of the rectangle is 3 times longer than the other. find the sides of the rectangle if its area is 108 cm ^ (2).

The area of a rectangle is equal to the product of its sides. Let’s designate the smaller side – x, then the other will be – 3x. The area is x * 3x, and by condition it is equal to 108
Let’s make the equation: x * 3x = 108
3x ^ 2 = 108
x ^ 2 = 36
x = 6
The smaller side is 6cm, and the larger side is 6 * 3 = 18cm.
Answer: 6cm, 18cm
