Since there are five numbers given it is assumed that the figure in question is a pentagon.
Unfortunately, a triangle is the only polygonal shape that is rigid. A pentagon, with all five sides of known lengths is not rigid - it can be flexed in the same way that a square can be flexed into a rhombus. The area of a rhombus can take any value from 0 up to the value of the square: the exact value is indeterminate. Similarly for a pentagon.

The area of rectangle is : 168.0
53.5 square cm to 1 d.p. Use the cosine rule to find an angle. Then use: Area = 1/2*a*b*sin C
Area is 98cm2
25cm x 25cm = 625cm
28x24=392 cm2
