Question

A 300 m long wire is used to fence a rectangular plot whose length is twice its width. Find the length and breadth of the plot.​

Answer 1

Step-by-step explanation:

$b = x \\ l = 2x \\ perimeter = 2 \times (l +b ) \\ 2 \times (2 x+ x) = 300 \\ 2 \times 3x = 300 \\ 3x = 300 \div 2 \\ 3x = 150 \\ x= 150 \div 3 \\ x= 50$
