| Let’s solve this problem using the equation.
Let the width of the rectangle be x centimeters, then the length of the rectangle is (x + 27) centimeters. By the condition of the problem, the perimeter is 110 centimeters. Let’s compose and solve the equation:
x + x + x + 27 + x + 27 = 110;
4x + 54 = 110;
4x = 110 – 54;
4x = 56;
x = 56: 4;
x = 14 centimeters – the width of the rectangle;
14 + 27 = 41 centimeters – the length of the rectangle;
14 * 41 = 574 cm ^ 2 – the area of the rectangle.
Answer: the area of the rectangle is 574 cm ^ 2.
