An artificial lake is the shape of a rectangle and has an area of 9/20 square miles the width of the lake is 1/5 the length of the lake what are the dimensions of the lake PLEASE PLEASE PLEASE PLEASE PLEASE HELP
Step 1 assume width is X then length equals 5 X the area of the lake 9/20 = 5X^2 So X^2 = 9/100 X = 3/10 so the width is 3/10 mile length 3/10 * 5 = 1 1/2 mile
