Ugh can someone show me the work for this? The length of a rectangle is 9.7 cm more than 4 times the width. If the perimeter of the rectangle is 91.4 cm, what are its dimensions?
Do you know perimeter formula of rectangular, then plug it in!
2 ( W + L ) = P -> W + L = P/2 => W +9.7 + 4w = 91.4 /2 @whadduptori Now can you finish it up!
