The rectangle is 5 cm long and 4 cm wider. find the perimeter of this rectangle.

Given: Rectangle; Length – 5 cm; Width – 4 cm>; P =?
Solution:
1) Find the width of the rectangle. To do this, add a number to the length of the rectangle, showing how much the width is greater than the length of the rectangle. b = 5 + 4 = 9 (cm); 2) The perimeter (P) of the rectangle is equal to twice the product of the length (a) and the height (b) of the rectangle, which can be written in the form of the formula: P = 2 * (a + b); P = 2 * (5 + 9) = 2 * 14 = 28 (cm);
Answer: 28 cm.
