    Ashley is digging for rocks at a geological site. She has 140 meters of rope and 4 stakes to mark off a rectangular area. Which set of dimensions will create a rectangle using all the rope Ashley has with her? 14 m × 10 m 70 m × 70 m 60 m × 10 m 55 m × 10 m @Michele_Laino

    If I call with x and y, the requested dimensions, then we have the subsequent consitions: \[\Large \begin{gathered} 2\left( {x + y} \right) = 140 \hfill \\ \hfill \\ x + y = 70 \hfill \\ \end{gathered} \]

    so you have to search for the option like n * m, such that n+m=70

    for example thge first option says: n=14 and m=10, so n+m=14+10= 24 which is not 70, so the first option is not correct!

    option B can not be the right one, since we have: m=N=70, and n+m=70+70=140, which is not 70
