Question from Erick, a student: A rectangular strip of land has a perimeter of 124meters and an area of 385 square meters. Find its possible dimensions |
Hi Erick,
Suppose the strip of land is $L$ meters long and $W$ meters wide.
Write the perimeter in terms of $L$ and $W.$ This is 124 meters so you have an equation in $L$ and $W.$
Write the area in terms of $L$ and $W.$ This is 385 square meters so you have a second equation in $L$ and $W.$
Solve the pair of equations for $L$ and $W.$
