A rectangular playground is enclosed by 440 feet of fencing. If the length of the playground is 20 feet less than 3 times the width, find the dimensions of the playground.

The dimensions of the playground are;Width = 60 feetLength = 160 feetHow to determine the dimensionsThe formula for calculating perimeter of a rectangle is expressed as;Perimeter = 2( l + w)Where;l is the length of the rectanglew is the width of the rectangleWe have the values as;Perimeter = 440 feetLength = 3w - 20Width = wNow, substitute the values into the formula, we have;440 = 2( 3w - 20 + w)expand the bracket440 = 2( 4w - 20)440 = 8w - 40collect like terms8w = 480Make 'w' the subject of formulaw = 60 feetLength = 3(60) - 20Length = 180 - 20Length = 160 feetHence, the values are 60feet and 160 feetLearn more about rectangles here:https://brainly.com/question/25292087#SPJ1
