Gọi độ dài mảnh đất ban đầu là x(m)

(Điều kiện: x>0)

Chiều dài mảnh đất mới là x+8(m)

Chiều rộng mảnh đất mới là x+4(m)

Diện tích mảnh đất đó tăng thêm 360m² nên ta có:

\(\left(x+8\right)\left(x+4\right)-x^2=360\)

=>\(x^2+12x+32-x^2=360\)

=>12x=360-32=328

=>\(x=\dfrac{328}{12}=\dfrac{82}{3}\left(nhận\right)\)

Diện tích mảnh đất ban đầu là \(\left(\dfrac{82}{3}\right)^2=\dfrac{6724}{9}\left(m^2\right)\)
