Gielh's Scribe post Text book Questions 5 , 12 , 16

5) Estimate each value to one decimal place .


12) While shopping online , Jin Hun finds a square rug with an area of 11m2 . He needs to know if it will fit in his 4m x 5m bedroom.

B) Estimate : √11 = 3.2

C) Yes it would fit because the side length is 3.3 its smaller than the shorter side of the room.

16) A fitness center will install square hot tub in a 6m x 6m room . They want the tub to fill no more than 75% of the rooms area.

75% of 36 is 0.75x36= 27
