Area = 35^2 X 0.2
Area = 245 sq km.

Anbu said: (Aug 23, 2017)  
FORM FACTOR = AREA/ LENGTH^2.

THEREFORE AREA= LENGTH^2/FORM FACTOR = 35^2 * .02 = 245 SQ KM.

Rizwan Ullah Wazir said: (Oct 8, 2020)  
Form factor = area of the basin/square of the axial length.
Area of the basin = (0.2)(35*2).
Area of the basin = 245 sq km.

Area of the basin = 0.2/35^2.
So, 245 sq km.
