From the condition, we know that the width of the rectangle is 10 cm. And it is also known that this is 14 cm less than its length. In order to find the perimeter of a rectangle, we first need to find its length.
The condition says that the length is 14 cm more than the width.
10 cm + 14 cm = 28 cm.
Now let’s remember and apply the formula for finding the perimeter of a rectangle.
The perimeter is equal to the sum of the lengths of all sides of the geometric figure.
P = 2 (a + b) is the perimeter of the rectangle.
P = 2 (10 + 28) = 2 * 38 = 76 cm.
Answer: 76 cm perimeter of the rectangle.
