A) 39 m
B) 42 m
C) 35 m
D) 53 m
Correct Answer: B
Solution :
: Perimeter of square = 56 m \[\Rightarrow \]\[4\times \]side of square = 56 m \[\Rightarrow \] Side of square \[=(56\div 4)=14\,m\] Now, \[AE+ED=14\text{ }m~\] \[\Rightarrow \] \[7\text{ }m+ED=14\text{ }m\] \[\Rightarrow \]\[ED=7\text{ }m\] So, AE = AF = £F = FB = BG = FG = 7 m and ED = CG = 7 m \[\therefore \] Perimeter of remaining figure \[=ED+DC+CG+GF+FE\] \[=(7+14+7+7+7)\,m=42\,m\]You need to login to perform this action.
