Calculate the perimeter of a rectangle whose sides are 7 cm, 9 cm, 6 cm, 10 cm and 12 cm.
Solution: Since the rectangle has five sides, it will be a pentagon.
The perimeter of a pentagon is equal to the sum of its sides, calculated by the formula:
P = a + b + c + d + e.
Substitute the existing values and get:
P = 7 + 9 + 6 + 10 + 12
P = 44
Answer: the perimeter of the rectangle is 44 cm.
