The area of the rectangle is found by the formula
S = ab, where a is length, b is width
1) 540: 27 = 20 (cm) – the length of the second side
The perimeter of a rectangle is found by the formula
P = 2 (a + b), where a is the length, b is the width
2) P = 2 * (27 + 20) = 2 * 47 = 94 (cm)
Answer: 94 cm
