Let's call the two remaining sides of the triangular land "a" and "b".
From the area and perimeter, we can find the length of the sides using the following formula:
Area = (a * b) / 2
And the perimeter is given by:
Perimeter = a + b + 26
We can substitute the given values for the area and perimeter:
336 = (a * b) / 2
84 = a + b + 26
Expanding the first equation:
672 = a * b
Solving for a in the second equation:
a = 84 - b - 26
Substituting the value of a in the first equation:
672 = (84 - b - 26) * b / 2
Expanding and simplifying the equation:
672 = 42b - 26b - 13 * b
Rearranging the equation:
672 = 9b - 338
Adding 338 to both sides:
1010 = 9b
Dividing both sides by 9:
b = 112.2
Finally, substituting the value of b back into the equation for a:
a = 84 - b - 26 = 84 - 112.2 - 26 = -54.2
Since a and b are the lengths of sides of a triangle, they must be positive values. The negative value for a means that the calculation is incorrect, and the given information is not sufficient to find the length of the remaining sides
