A) Tripled
B) Doubled
C) Halved
D) Remains the same
Correct Answer: B
Solution :
Length\[(\ell )\], Breadth\[(b)\] \[\Rightarrow \] \[P=2(\ell +b)\]units When length and breadth are doubled, \[l\to 2l\] \[b\to 2b\] Then \[P=2(2l+2b)\] \[=2\times [2(l+b)]=2\times P\] \[i.e.,\]perimeter is doubled.You need to login to perform this action.
