alleryThe perimeter of a rectangle with length a and width b is:
Aa + b
Bab
C2(a + b)
D2ab
Answer & Solution
Correct answer: C. 2(a + b)
A rectangle has two equal pairs of opposite sides — length a and width b.
Perimeter = a + b + a + b = 2(a + b).
For a square (special case with a = b), this becomes 4a.
