Okay, this problem says the diagonals of a concrete rectangular slab are equal, indicating the shape is perpendicular.
00:09
But the plans are in feet, and you measured in inches.
00:15
So, i need to come and you got 426 inches for the diagonal.
00:20
So, we want that in feet.
00:22
426 inches, and we want it in feet.
00:29
So, we're gonna say 12 inches is 1 foot.
00:35
And see, inches will cancel out because it's on top and bottom.
00:39
So, 426 divided by 12, that's 3, that's 36, 66, 5 is 60, and 1 half.
00:52
So, the diagonal is 35 .5 feet.
01:04
Okay, then it says, in addition to the 426 inch diagonal, the rectangular slab is 50 inches wide.
01:13
What is the length in inches? alright, now look, this is making a right triangle, and we know that the width is 50 inches, and we know that this diagonal is 426 inches...
