A) 32cm
B) 16cm
C) 64 cm
D) Cannot be determined
Correct Answer: A
Solution :
Breadth of rectangle = \[x\] cm \[\therefore \] Length \[=(x+48)\] cm \[\Rightarrow \] \[4x=x+48\] \[\Rightarrow \] \[3x=48\] \[\Rightarrow \] \[x=\frac{48}{3}=16\] Length of rectangle \[=48+16=64\] cm \[\therefore \] Area of square = Area of rectangle \[=(16\,\,\,\,64)\] sq. cm. \[\therefore \] Side of square \[=\sqrt{16\,\,\,\,\,\,64}\] \[=32\] cmYou need to login to perform this action.
