Measure the linear dimensions in cm and then calculate the area using the appropriate formula.
or
measure the linear dimensions in metres, calculate the area and mutiply by 10000
or
measure the linear dimensions in millimetres, calculate the area and divide by 100.

A surface area of 804.2 cm2
50.26 cm2
Areas are a square dimension. So I assume you meant what are the sides of a square with area 25 cm2? Area_square = side2 ⇒ side = √area = √(25 cm2) = 5 cm
Area of square = (length of side)2 = (10cm)2 = 10*10 cm2 = 100 cm2
Formula: kg/cm2 x 9.807 = newtons/cm2
A = 38.52 cm2
40 cm2
Area = 33.2 cm2
1 * 11 = 11 cm2 2 * 10 = 20 cm2 3 * 9 = 27 cm2 4 * 8 = 32 cm2 5 * 7 = 35 cm2 6 * 6 = 36 cm2 7 * 5 = 35 cm2 8 * 4 = 32 cm2 9 * 3 = 27 cm2 10 * 2 = 20 cm2 11 * 1 = 11 cm2

A volume cannot be 64 cm2. A volume is not measured in cm2 so the question is based on unreliable information.
