Answer : Option B
Explanation :
The perimeter: 2 (L + B) = 210 or L+ B = 105 ...... (i)
As per the question: (L - B) = 25 ....... (ii)
Solving the above two equations:
L + B = 105
B = 105 - L
Put the value of B in (ii).
L - (105 - L) = 25
L - 105 + L = 25
2L = 25 + 105
2L = 130
L = 65
So, - B = 105 - 65 = 40
Now, area of a rectangle: L *B= 65 * 40 = 2600 m2
