A) 2
B) 8
C) 9
D) 18
Correct Answer: C
Solution :
Let L and B be length and breadth of rectangle respectively. Then, 2(L + B) = 36 Then, 2(L + B) = 36 \[L+B+\frac{36}{2}=18\] We have to find number of pairs of natural numbers whose sum is 18. These are (1, 17) (2, 16) (3, 15) (4, 14) (5, 13) (6, 12) (7, 11) (8, 10) (9, 9) Which are 9 in number.You need to login to perform this action.
