the length of a rectangular field is 7 / 5 its width . if the perimeter of the field is 432 meters , what is the width of the field ?
"let l be the length and w be the width . l = ( 7 / 5 ) w perimeter : 2 l + 2 w = 432 , 2 ( 7 / 5 ) w + 2 w = 432 solve the above equation to find : w = 90 m and l = 126 m . correct answer e ) 90"
divide(432, add(add(divide(7, 5), divide(7, 5)), const_2))
