For this case we can make the following rule of three:
38 milimeters ---------> 6 meters
57 milimeters ---------> x
Clearing x we have:
x = (57/38) * (6)
x = 9 meters
Answer:
the current length of the living room is:
x = 9 meters
Check the picture below.
now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.

Paaralellogram has 2 pairs of paralell sidess
therefor there are 2 pairs of sides with same legnth
perimiter=legnth+widht+legnth+width since the opposite sides ar the same sinnce paralell
perimiter=2legnth +2width
perimiter=15.42
legnth=2.93
subsitute
15.42=2(2.93)+2width
15.42=5.86+2width
subtract 5.86 from both sides
9.56=2width
divide both sides by 2
4.78
legth of ther side is 4.78 cm
Answer:
∠GAC ≅ ∠HFD by the Property of Congruence.
Step-by-step explanation:
I'm going to be honest the question is a little confusing cause of the beginning, but if you're looking for which angles are actually congruent it's ∠GAC ≅ ∠HFD
