irina [24]

Answer:

New bed dimension of bed 0.5 ft, 0.25 ft

New bed dimension of room 1.16 ft, 1.33 ft

Step-by-step explanation:

Given data:

bed dimension is given as 6 ft by 3 ft

room dimension is given as 14 ft 16 ft

according to the given information , new dimension of the room and bed will be 1/12 times of actual dimension. therefore we have

New bed dimension of bed = \frac{1}{12} \times 6 ft, \frac{1}{12} \times 3 ft

                                 = 0.5 ft, 0.25 ft

New bed dimension of room = \frac{1}{12} \times 14 ft, \frac{1}{12} \times 16 ft

                                                 = 1.16 ft, 1.33 ft
