The sides of the rectangle are 15 and 10. Find the area of the rectangle.

We are faced with a simple geometric problem, which can be solved in just one action, if you know the required formula.
Let’s compose a short condition for the problem and solve it:
The shape is a rectangle;
First side – 15;
Second side – 10;
Square – ?;
Let’s remember what the area of the rectangle is.
The area of a rectangle is equal to the product of its sides:
S = a * b;
Since we know the lengths of both sides of the rectangle, we can find its area without additional actions:
S = 15 * 10 = 150 – area;
Answer: 150.
