M20. If a rectangle has a length of 12 cm and a width of 5 cm, what is its perimeter?
a) 22 cm
b) 24 cm
c) 34 cm
d) 60 cm
ANSWER: c) 34 cm
EXPLANATION:
The perimeter of a rectangle can be calculated by adding up all its sides. In this case, the rectangle has a length of 12 cm and a width of 5 cm.
To find the perimeter, we can use the formula:
Perimeter = 2 × (Length + Width)
Substituting the given values:
Perimeter = 2 × (12 cm + 5 cm)
Perimeter = 2 × 17 cm
Perimeter = 34 cm
Therefore, the perimeter of the rectangle is 34 cm.
