4.5 (4-x)+36=202-2.5(3x+28)
45 (4-x)+360=2020-25(3x+28)
-45x+540=-75x+1320
-45x+540-540=-75x+1320-540
-45x=-75x+780
-45x+75x=-75x+780+75x
30x=780
30x/30= 780/30

Answer:
768 tiles would be required to tile the floor.
Step-by-step explanation:
Let's first calculate the number of square meters that the rectangular floor represents, by using the formula for the area of a rectangle (length x width):
Floor area = 8 m x 6 m = 48
Next, let's convert the side of the square tiles into meters in order to keep the same units in both (floor area an tile area):
25 cm = 0.25 m
Then the are of a square tile can be obtained by the formula 0.25 m x 0.25 m = 0.0625
Now to find the number of tiles needed, we perform the division of the total floor area to be covered divided by the area covered by a single tile:
Number of tiles needed: 48 / 0.0625 = 768 tiles
If the angles are below 90 degrees this would make this triangle an acute triangle
