Uncle Wang's new living room is 9. 1 m long and 4.5 m wide. He is going to use a square brick with a side length of 0.8m to pave the floor, 50 yuan.

Area of rectangle = length x width

So the area =9. 1x4.5=40.95 square meters.

Floor tile area = 0,8x0,8 = 0,64m2.

Brick required: 40.95÷0.64≈64.

64>50

So 50 yuan is not enough.
