The perimeter of a rectangle whose length is 128 cm is 410 cm, find its width and area.

In order to find the area of a rectangle, we must know both the length and the width of the rectangle.

Let’s start by looking at a condition. It is known that the perimeter of a rectangle with a length of 128 cm is 410 cm. Let’s start by remembering and applying the formula for finding the perimeter of a rectangle.

P = 2 (a + b);

2 (x + 128) = 410;

x + 128 = 410: 2;

x + 128 = 205;

x = 205 – 128;

x = 77 cm width of the rectangle.

S = a * b = 128 * 77 = 9 856 cm2 area of a rectangle.

Answer: 77 cm wide and 9 856 cm2 area of a rectangle
