A) 2240
B) 2142
C) 2269
D) 2025
E) 2340
Correct Answer: A
Solution :
Let the length be 7x and the breadth be 5x. Now, the perimeter of the rectangle \[=\frac{4800}{25}=192\,m\] Then, 2(7x + 5x) = 192 or, 52x = 96 \[\therefore \]\[x=8\] Hence, length\[=7\times 8=56\,m\] Breadth \[=5\times 8=40\,m\] \[\therefore \] Area of the rectangular plate\[=56\times 40\] = 2240 sq mYou need to login to perform this action.
