The perimeter of a rectangle is calculated as the sum of its length and width multiplied by two.
Let the width of the rectangle be x cm, then we get the equation:
2 * (26 + x) = 84
26 + x = 84/2
26 + x = 42
x = 42-26
x = 16
The width of the rectangle is 16 cm.
The area of a rectangle is calculated as the product of its length and width.
1) 16 cm * 26 cm = 416 cm2 area of a rectangle.
Answer: the area of the rectangle is 416 cm2.
