A) 30 m
B) 40 m
C) 50 m
D) 60 m
Correct Answer: C
Solution :
Suppose the length and breadth of rectangle is l and b respectively. and side of a square = a m Then, \[4a=160\] \[a=40\] And \[2\,\,(l+b)=160\] \[l+b=80\] ?.. (1) Now, \[l\times b+100={{a}^{2}}\] \[l\times b+100=1600\] \[l\times b=1500\] ?? (2) On solving eqn. (1) and (2) = 50 m and b = 30 m Hence, the length of the rectangle is 50 m.You need to login to perform this action.
