Answer:
the room square side is 4.8m
Area of the room is= 4.8=²23.04²m
perimeter of square tiles=4a =1.2
a=1.2/4
or a=o.3m
area of the square tiles =0.3²=0.09m²
numbers of the tiles are rcover floor of the room
23.0.4/0.09=256
each tiles cost Rs 27
the total cost=256*27=6912
the th coalst cover by the th floor is Rs .6912

IfIf it forms interior <6 measuring70. The measure of <4 is: B. 110°.
<h3>Measure of <4</h3>
Using this interior angle theorem
Measure of <4=180° - <6
Where:
<6 measure 70
Hence:
Measure of <4=180°-70°
Measure of <4=110°
Therefore the measure of <4 is: B. 110°.
