The perimeter of the rectangle is equal to the perimeter of the square 38 dm. Find the length of the rectangle if its width is 28 cm.
In order to find the length of the rectangle, we will apply the formula to find the perimeter.
So, first of all, we will consider the condition of the problem. It says that the perimeter of the rectangle is 38 inches. It is also known that its width is 28 cm.
Let’s translate the perimeter into centimeters:
38 dm = 38 * 10 = 380 cm.
The perimeter of the rectangle is searched for using the following formula:
P = 2 (a + b);
Let x cm be the length of the rectangle.
2 (x + 28) = 380;
x + 28 = 380: 2;
x + 28 = 190;
x = 190 – 28;
x = 162 cm rectangle length.
Answer: 162 cm is the length of the rectangle.
