The perimeter P of the rectangle is 14 centimeters.
The length a of this quadrangle is 6 centimeters.
We calculate the width of this figure by the formula b = (P – a – a): 2:
b = (P – a – a): 2 = (14 – 6 – 6): 2 = 2: 2 = 1 centimeter.
We calculate the area of the rectangle using the formula S = a * b:
S = a * b = 6 * 1 = 6 cm2.
Answer: The rectangle covers an area of 6 cm2.
