The length of a rectangular rug is given as 0.9m, correct to the nearest ten centimeters .The width of the rug is given as 0.6m, correct to the nearest ten centimeters. Find the lower bounds, in meters, of the perimeter of the rug.
The lowest bound step 1 is change to measures of m to cm =900 lower bound = 895 and 600 = 595 to nearest 10 cm Therefore ; 895 + 895 + 595 + 595 = 2980 cm = p(cm) ≥ 2980
