The perimeter of square \[\mathbf{X}\] is\[\mathbf{20}\,\,\mathbf{cm}\], and that of square \[\mathbf{Y}\] is\[\mathbf{36}\,\,\mathbf{cm}\]. |
A) \[4\,\,cm\]
B) \[5\,\,cm\]
C) \[14\,\,cm\]
D) \[9\,\,cm\]
Correct Answer: A
Solution :
Perimeter of square \[X\] is\[20\,\,cm\]. So, its side \[=\frac{20}{4}cm=5\,\,cm\] Perimeter of square \[Y\] is\[36\,\,cm\]. So, its side\[=\frac{36}{4}cm=9\,\,cm\] Hence, their difference\[=(9-5)cm=4\,\,cm\]You need to login to perform this action.
