Answer» ANSWER: Step-by-step explanation: Let the BREADTH of the floor be x meters so, Lenght of the room = 1x/2 +x meters = 3x/2 meters Rate of carpeting the floor = 38.50 PER m**2 Total cost of carpeting the room = 924 ATQ Lenght × Breadth × 38.50 = 924 x × 3x/2 × 38.50 = 924 3x**2/2 × 38.50 = 924 3x**2 × 19.25 = 924 3x**2 = 924 ÷ 19.25 3x**2 = 48 x**2 = 16 x = 4 meters so, lenght = 6 meters breadth = 4 meters |
