Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Length = 80 m and breadth = 60 m If one moves along the two adjacent sides, one covers 80+60 = 140 m. Diagonal of the rectangle = √ ( length^2 + breadth^2) ...
The answer is 80, 2x+3x+4x=180, so x=20. 20*4=80.
