[tex]four \: sides \: = 40 {x}^{2} + 16 {x}^{2} \\ one \: side \: =(40 {x}^{2} + 16 {x}^{2}) \div 4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 10 {x}^{2} + 4 {x}^{2} \\ area \: \: \: \: \: \: \: \: \: = length \: \times breath \\ \: \: \: \: = (10 {x}^{2} + 4 {x}^{2}) \times (10 {x}^{2} + 4 {x}^{2}) \\ = 100 {x}^{4} + 40 {x}^{4} + 40 {x}^{4} + 16 {x}^{4} \\ \ = 196 {x}^{4} [/tex]
