Yes an area problem must have an squared unit. Suppose: Find the area of a suare with side 8 cm. Thus, 8 squared will be 64cm. Your answer will be 64 squared cm.
56 cm squared
2500 cm squared
The answer to your question is 8 cm diameter, increasing to 16 cm diameter: r2 squared = 4 x r1 squared and r2 = r1 + 4 r1 squared + 8r1 + 16 = 4r1 squared 3r1 squared - 8r1 - 16 = 0 Factors are (3r1 + 4)(r1 - 4), so original radius was 4cm (area 16pi) and increased radius is 8 cm (area 64pi).
As squared meters are two-dimensional and cm are one- dimensional it is not possible. If you meant cm squared then: 1 Meter squared = 10000 Centimeter squared. Using this you can use simple multiplication to convert.
