A) 32 m
B) 8 m
C) 4 m
D) 16 m
Correct Answer: A
Solution :
Let the length and breadth of rectangle are a and b respectively. According to the question, \[2(a+b)=160\] \[\Rightarrow \] \[a+b=80\] ?(i) \[\Rightarrow \] \[\frac{a-b=48}{2a=128}\] ?(ii) \[\Rightarrow \] \[a=\frac{128}{2}=64\,m\] From Eq. (i), \[b=80-64=16m\] \[\therefore \] Area of rectangle \[=64\times 16\,{{m}^{2}}\] \[\Rightarrow \] \[{{(Side)}^{2}}=64\times 16\] \[\Rightarrow \] \[Side=8\times 4=32\,m\]You need to login to perform this action.
