Answer:
40 ft × 75 ft
Step-by-step explanation:
Let x be the one side ( in feet ) of the rectangular parcel,
So, the diagonal between opposite corners = ( x + 10 ) feet,
Let y be the other side of the rectangle ( adjacent to side x ),
The area of the rectangle,
A = x × y,
According to the question,
A = 3000 square ft,
∵ In a rectangle,
Where, a and b are the adjacent side of the rectangle and D is the diagonal,
By graphing the equation,
We found that,
The only real zeros of the equation is at x = 75,
Hence, the one side of the rectangle = 75 ft,
And, second side = = 40 ft
Hence, the dimension of the land is 40 ft × 75 ft
