A carpenter measured the dimensions of the floor in a rectangular room.
00:04
He rounded the measurements to the nearest foot and recorded them as shown, width of nine feet and a length of 15 feet.
00:15
So this is what is written on the right side of our blackboard or whiteboard, a 9 feet by 15 feet rectangular room.
00:23
Based on the rounded measurements, which of the following statements could be true.
00:27
The actual width of the floor is 8 .4 inches.
00:33
So this is her width.
00:37
This is her length.
00:39
The problem said that they rounded, here it is, you rounded the measurements to the nearest foot.
00:48
So when you round something up or down, you round up when it's 0 .5.
01:01
And up round down when it's less okay less than 0 .5 okay so let's look at the problem the actual width of the floor is 8 feet 4 inches so if this is true our width should have been 8 feet so we know that a is incorrect you can just delete that one b the actual length of the floor is 15 .5 remember when we round up, this is supposed to have been 16 feet, but we only have 15.
01:41
So this was not around, this is not correct either...
