The width of a rectangle is 6 kilometers less than twice its length. if the area of the rectangle is 176 square kilometers, find the dimensions of the rectangle
Let w and 2w-6 be the width and length, respectively. Then: w(2w-6)=176 2w²-6w-176=0 (2w+16)(w-11 )=0 w=-16/2 or 11 If the width is 11 km, then the length is 16 km ☺☺☺☺
